programming - C - function isgraphWhat links here?

Description

The isgraph() function tests for any printing character except the space character, that is, any character for which int isalnum(int c) or int ispunct(int c) is true.

The behavior of the isgraph() function is affected by the current locale. To modify the behavior, change the LC_CTYPE category in setlocale(), that is, setlocale(LC_CTYPE, newlocale). In the C locale or in a locale where character type information is not defined, characters are classified according to the rules of the U.S. ASCII 7-bit coded character set.

Parameters



Return Values

The isgraph() function returns non-zero for true and zero for false. If the parameter is not in the domain of the function, the return result is undefined.
