Functions

VALUE rb_errinfo (void)
 This is the same as $! in Ruby. More...
 
void rb_set_errinfo (VALUE err)
 Sets the current exception ($!) to the given value. More...
 
void rb_raise (VALUE exc, const char *fmt,...)
 Exception entry point. More...
 
void rb_fatal (const char *fmt,...)
 Raises the unsung "fatal" exception. More...
 
void rb_bug (const char *fmt,...)
 Interpreter panic switch. More...
 
void rb_bug_errno (const char *msg, int err)
 This is a wrapper of rb_bug() which automatically constructs appropriate message from the passed errno. More...
 
void rb_sys_fail (const char *msg)
 Converts a C errno into a Ruby exception, then raises it. More...
 
void rb_sys_fail_str (VALUE msg)
 Identical to rb_sys_fail(), except it takes the message in Ruby's String instead of C's. More...
 
void rb_mod_sys_fail (VALUE mod, const char *msg)
 Identical to rb_sys_fail(), except it takes additional module to extend the exception object before raising. More...
 
void rb_mod_sys_fail_str (VALUE mod, VALUE msg)
 Identical to rb_mod_sys_fail(), except it takes the message in Ruby's String instead of C's. More...
 
void rb_readwrite_sys_fail (enum rb_io_wait_readwrite waiting, const char *msg)
 Raises appropriate exception using the parameters. More...
 
void rb_iter_break (void)
 Breaks from a block. More...
 
void rb_iter_break_value (VALUE val)
 Identical to rb_iter_break(), except it additionally takes the "value" of this breakage. More...
 
void rb_exit (int status)
 Terminates the current execution context. More...
 
void rb_notimplement (void)
 
VALUE rb_syserr_new (int err, const char *msg)
 Creates an exception object that represents the given C errno. More...
 
VALUE rb_syserr_new_str (int n, VALUE arg)
 Identical to rb_syserr_new(), except it takes the message in Ruby's String instead of C's. More...
 
void rb_syserr_fail (int err, const char *msg)
 Raises appropriate exception that represents a C errno. More...
 
void rb_syserr_fail_str (int err, VALUE msg)
 Identical to rb_syserr_fail(), except it takes the message in Ruby's String instead of C's. More...
 
void rb_mod_syserr_fail (VALUE mod, int err, const char *msg)
 Identical to rb_mod_sys_fail(), except it does not depend on C global variable errno. More...
 
void rb_mod_syserr_fail_str (VALUE mod, int err, VALUE msg)
 Identical to rb_mod_syserr_fail(), except it takes the message in Ruby's String instead of C's. More...
 
void rb_readwrite_syserr_fail (enum rb_io_wait_readwrite waiting, int err, const char *msg)
 Identical to rb_readwrite_sys_fail(), except it does not depend on C global variable errno. More...
 
void rb_unexpected_type (VALUE self, int t)
 Fails with the given object's type incompatibility to the type. More...
 
void rb_warning (const char *fmt,...)
 Issues a warning. More...
 
void rb_category_warning (rb_warning_category_t cat, const char *fmt,...)
 Identical to rb_warning(), except it takes additional "category" parameter. More...
 
void rb_compile_warning (const char *file, int line, const char *fmt,...)
 Issues a compile-time warning that happens at __file__:__line__. More...
 
void rb_sys_warning (const char *fmt,...)
 Identical to rb_sys_fail(), except it does not raise an exception to render a warning instead. More...
 
void rb_warn (const char *fmt,...)
 Identical to rb_warning(), except it reports unless $VERBOSE is nil. More...
 
void rb_category_warn (rb_warning_category_t cat, const char *fmt,...)
 Identical to rb_category_warning(), except it reports unless $VERBOSE is nil. More...
 
void rb_compile_warn (const char *file, int line, const char *fmt,...)
 Identical to rb_compile_warning(), except it reports unless $VERBOSE is nil. More...
 
void rb_category_compile_warn (rb_warning_category_t cat, const char *file, int line, const char *fmt,...)

Warning
Symbols prefixed with either RBIMPL or rbimpl are implementation details. Don't take them as canon. They could rapidly appear then vanish. The name (path) of this header file is also an implementation detail. Do not expect it to persist at the place it is now. Developers are free to move it anywhere anytime at will.
Note
To ruby-core: remember that this header can be possibly recursively included from extension libraries written in C++. Do not expect for instance __VA_ARGS__ is always available. We assume C99 for ruby itself but we don't assume languages of extension libraries. They could be written in C++98.
