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. __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. Definition in file ctype.h.

inlinestatic |
Queries if the passed pointer points to a newline character.
What is a newline and what is not depends on the passed encoding.
[in] | p | Pointer to a possibly-middle of a character. |
[in] | end | End of the string. |
[in] | enc | Encoding. |
false | It isn't. |
true | It is. |
|
inlinestatic |
Identical to rb_isalnum(), except it additionally takes an encoding.
[in] | c | A code point. |
[in] | enc | An encoding. |
true | enc classifies c as "ANUM". |
false | Otherwise. |
|
inlinestatic |
Identical to rb_isalpha(), except it additionally takes an encoding.
[in] | c | A code point. |
[in] | enc | An encoding. |

|
inlinestatic |
Identical to rb_isascii(), except it additionally takes an encoding.
[in] | c | A code point. |
[in] | enc | An encoding. |
false | c is out of range of ASCII character set in enc . |
true | Otherwise. |
