isphonogram,
isphonogram_l — phonographic
character test
Standard C Library (libc, -lc)
#include
<ctype.h>
int
isphonogram(int
c);
int
isphonogram_l(int
c, locale_t
loc);
The
isphonogram()
and isphonogram_l() functions test for a
phonographic character.
The
isphonogram_l()
function takes an explicit locale argument, whereas the
isphonogram() function uses the current global or
per-thread locale.
The isphonogram() and
isphonogram_l() functions return zero if the
character tests false and return non-zero if the character tests true.
The isphonogram() function appeared in
4.4BSD.
