It is a predicate returning non-zero when <[c]> represents an -alphabetic ASCII character, and 0 otherwise. It is defined only when -<<isascii>>(<[c]>) is true or <[c]> is EOF. +alphabetic ASCII character, and 0 otherwise. It is defined only if +<[c]> is representable as an unsigned char or if <[c]> is EOF. You can use a compiled subroutine instead of the macro definition by undefining the macro using `<<#undef isalpha>>'. |
