ISWGRAPH(3) | Linux Programmer's Manual | ISWGRAPH(3) |
NAME¶
iswgraph - test for graphic wide characterSYNOPSIS¶
#include <wctype.h>int iswgraph(wint_t wc);
DESCRIPTION¶
The iswgraph() function is the wide-character equivalent of the isgraph(3) function. It tests whether wc is a wide character belonging to the wide-character class "graph". The wide-character class "graph" is a subclass of the wide-character class "print". Being a subclass of the wide-character class "print", the wide-character class "graph" is disjoint from the wide-character class "cntrl". The wide-character class "graph" is disjoint from the wide-character class "space" and therefore also disjoint from its subclass "blank". The wide-character class "graph" contains all the wide characters from the wide-character class "print" except the space character. It therefore contains the wide-character classes "alnum" and "punct".RETURN VALUE¶
The iswgraph() function returns nonzero if wc is a wide character belonging to the wide-character class "graph". Otherwise it returns zero.CONFORMING TO¶
C99.NOTES¶
The behavior of iswgraph() depends on the LC_CTYPE category of the current locale.SEE ALSO¶
