isphonogram, isphonogram_l – phonographic character test

LIBRARY SYNOPSIS DESCRIPTION RETURN VALUES SEE ALSO HISTORY

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 BSD 4.4 .
