isgraph, iswgraph, _isgraph_l, _iswgraph_l
Determines whether an integer represents a graphical character.
int isgraph( int c ); int iswgraph( wint_t c ); int _isgraph_l( int c, _locale_t locale ); int _iswgraph_l( wint_t c, _locale_t locale );
Integer to test.
Each of these routines returns nonzero if c is a particular representation of a printable character other than a space. isgraph returns a nonzero value if c is a printable character other than a space. iswgraph returns a nonzero value if c is a printable wide character other than a wide character space. Each of these routines returns 0 if c does not satisfy the test condition.
The versions of these functions that have the _l suffix use the locale that's passed in instead of the current locale for their locale-dependent behavior. For more information, see Locale.
The behavior of isgraph and _isgraph_l is undefined if c is not EOF or in the range 0 through 0xFF, inclusive. When a debug CRT library is used and c is not one of these values, the functions raise an assertion.
