Enumeration Type Documentation

◆ rb_io_wait_readwrite

enum rb_io_wait_readwrite

for rb_readwrite_sys_fail first argument

Definition at line 73 of file error.h.

◆ rb_warning_category_t

enum rb_warning_category_t

Warning categories.

A warning issued using this API can be selectively requested / suppressed by the end-users. For instance passing -W:no-deprecated to the ruby process would suppress those warnings in deprecated category.

Warning: There is no way to declare a new category (for now).

Enumerator
RB_WARN_CATEGORY_NONE	Category unspecified.
RB_WARN_CATEGORY_DEPRECATED	Warning is for deprecated features.
RB_WARN_CATEGORY_EXPERIMENTAL	Warning is for experimental features.
RB_WARN_CATEGORY_PERFORMANCE	Warning is for performance issues (not enabled by -w).
RB_WARN_CATEGORY_STRICT_UNUSED_BLOCK	Warning is for checking unused block strictly.

Function Documentation

◆ rb_bug()

void rb_bug	(	const char *	fmt,
			...
	)

Interpreter panic switch.

Immediate process termination without any synchronisations shall occur. LOTS of internal states, stack traces, and even machine registers are displayed if possible for debugging purposes then.

Warning: Do not use this API.; You are not expected to use this API.; Why not just fix your code instead of calling this API?; It was a bad idea to expose this API to extension libraries at the first place. We just cannot delete it at this point for backwards compatibility. That doesn't mean everyone are welcomed to call this function at will.

Parameters

◆ rb_exit()

void rb_exit ( int status )

Terminates the current execution context.

This API is the entry point of a "well-mannered" termination sequence. When called from an extension library, it raises rb_eSystemExit exception. Programs could rescue that exception. Can cancel process exit then. Otherwise, that exception results in a process termination with the status passed to this function.

Parameters

[in] status Exit status, see also exit(3).

Exceptions

rb_eSystemExit Exception representing the exit status.

Note: It never returns.

Referenced by rb_f_abort(), and rb_thread_kill().

◆ rb_fatal()

void rb_fatal	(	const char *	fmt,
			...
	)

Raises the unsung "fatal" exception.

This is considered severe. Nobody can rescue the exception. Once raised, process termination is inevitable. However ensure clauses still run, so that resources are properly cleaned up.

Parameters

[in] fmt Format specifier string compatible with rb_sprintf().

Exceptions

rb_eFatal An exception that you cannot rescue.

Note: It never returns.

Definition at line 3687 of file error.c.

◆ rb_frozen_error_raise()

Parameters

[in]	recv	What is frozen.
[in]	fmt	Format specifier string compatible with rb_sprintf().

Exceptions

rb_eFrozenError Always raises this.

Note: It never returns.

◆ rb_iter_break()

void rb_iter_break ( void )

Breaks from a block.

Because you are using a CAPI this is not as intuitive as it sounds. In order for this function to properly work, make a rb_block_call_func_t function that calls it internally, and pass that function to rb_block_call().

Exceptions

rb_eLocalJumpError Called from outside of a block.

Note: It never returns.

Definition at line 2076 of file vm.c.

◆ rb_iter_break_value()

void rb_iter_break_value ( VALUE val )

Identical to rb_iter_break(), except it additionally takes the "value" of this breakage.

It will be the evaluation result of the iterator. This is kind of complicated; you cannot see this as a "return from a block" behaviour. Take a look at this example:

def foo(q)
  puts(w = yield(q))
  puts(e = yield(w))
  puts(r = yield(e))
  puts(t = yield(r))
  puts(y = yield(t))
  return "howdy!"
end
 
x = foo(0) {|i|
  if i > 2
    break "hello!"
  else
    next i + 1
  end
}
 
puts x

This script outputs 1, 2, 3, and hello. Note that the value passed to break becomes the return value of foo method, not the value of yield. This is confusing, but can be handy on occasions e.g. when you want to bring a local variable out of a block.

Parameters

[in] val The value of the iterator.

Exceptions

rb_eLocalJumpError Called from outside of a block.

Note: It never returns.

Definition at line 2082 of file vm.c.

◆ rb_loaderror()

◆ rb_loaderror_with_path()

void rb_loaderror_with_path	(	VALUE	path,
		const char *	fmt,
			...
	)

Identical to rb_loaderror(), except it additionally takes which file is unable to load.

The path can be obtained later using LoadError#path of the raising exception.

Parameters

[in]	path	What failed.
[in]	fmt	Format specifier string compatible with rb_sprintf().

Exceptions

rb_eLoadError Always raises this.

Note: It never returns.

An equivalent of rescue clause.

First it calls the function b_proc with data1 as the argument. If nothing is thrown the function happily returns the return value of b_proc. When b_proc raises an exception, and the exception is a kind of one of the given exception classes, it then calls r_proc with data2 and that exception. If the exception does not match any of them, it propagates.

Parameters

[in]	b_proc	A function which potentially raises an exception.
[in,out]	data1	Passed to `b_proc`.
[in]	r_proc	A function which rescues an exception in `b_proc`.
[in,out]	data2	The first argument of `r_proc`.
[in]	...	1 or more exception classes. Must be terminated by `(VALUE)0`

Returns: The return value of b_proc if no exception occurs, or the return value of r_proc otherwise.

◆ rb_set_errinfo()

void rb_set_errinfo ( VALUE err )

Sets the current exception ($!) to the given value.

Parameters

[in] err An instance of rb_eException, or RUBY_Qnil.

Exceptions

rb_eTypeError What is given was neither rb_eException nor RUBY_Qnil.

Definition at line 1926 of file eval.c.

◆ rb_sys_fail()

void rb_sys_fail ( const char * msg )

Converts a C errno into a Ruby exception, then raises it.

foo(VALUE argv)
{
   const auto cmd = StringValueCStr(argv);
   const auto waitr = system(cmd);
   if (waitr == -1) {
       rb_sys_fail("system(3posix)"); // <-------------- this
   }
   else {
       return INT2FIX(fd);
   }
}

Parameters

[in] msg Additional message to raise.

Exceptions

rb_eSystemCallError An exception representing errno.

◆ rb_unexpected_type()

void rb_unexpected_type	(	VALUE	self,
		int	t
	)

Fails with the given object's type incompatibility to the type.

It seems this function is visible from extension libraries only because RTYPEDDATA_TYPE() uses it on RUBY_DEBUG. So you can basically ignore it; use some other fine-grained method instead.

Parameters

[in]	self	The object in question.
[in]	t	Expected type of the object.

Exceptions

rb_eTypeError self not in type t.

Note: It never returns.; The second argument must have been an enum ruby_value_type, but for historical reasons it remains to be an int (in other words we see no benefits fixing this bug).

◆ rb_vrescue2()

VALUE rb_vrescue2	(	VALUE(*)(VALUE)	b_proc,
		VALUE	data1,
		VALUE(*)(VALUE, VALUE)	r_proc,
		VALUE	data2,
		va_list	ap
	)

Identical to rb_rescue2(), except it takes va_list instead of variadic number of arguments.

This is exposed to 3rd parties because inline functions use it. Basically you don't have to bother.

Parameters

[in]	b_proc	A function which potentially raises an exception.
[in,out]	data1	Passed to `b_proc`.
[in]	r_proc	A function which rescues an exception in `b_proc`.
[in,out]	data2	The first argument of `r_proc`.
[in]	ap	1 or more exception classes. Must be terminated by `(VALUE)0`

Returns: The return value of b_proc if no exception occurs, or the return value of r_proc otherwise.

	)

Identical to rb_warning(), except it reports unless $VERBOSE is nil.

Note: This function is affected by the value of $VERBOSE, it does nothing if $VERBOSE is nil.

Parameters

[in] fmt Format specifier string compatible with rb_sprintf().

◆ rb_warning()

void rb_warning	(	const char *	fmt,
			...
	)

Issues a warning.

In ruby, warnings these days are tightly coupled with the rb_mWarning constant and its warn singleton method. This CAPI is just a thin wrapper of it; everything passed are formatted like what rb_sprintf() does, then passed through to the method. Programs can have their own def Warning.warn at will to do whatever they want, from ignoring the warnings at all to sinking them to some BigQuery data set via a Fluentd cluster. By default, the method just emits its passed contents to rb_stderr using rb_io_write().

Note: This function is affected by the value of $VERBOSE, it does nothing unless $VERBOSE is true.

Parameters

[in] fmt Format specifier string compatible with rb_sprintf().
