DESCRIPTION |
<<isalpha>> is a macro which classifies ASCII integer values by table |
lookup. 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>>'. |
