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.
