ISIDEOGRAM(3) FreeBSD Library Functions Manual ISIDEOGRAM(3)
NAME
isideogram, isideogram_l - ideographic character test
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <ctype.h>
int
isideogram(int c);
int
isideogram_l(int c, locale_t loc);
DESCRIPTION
The isideogram() and isideogram_l() functions test for an ideographic
character.
The isideogram_l() function takes an explicit locale argument, whereas
the isideogram() function use the current global or per-thread locale.
RETURN VALUES
The isideogram() and isideogram_l() functions return zero if the
character tests false and return non-zero if the character tests true.
COMPATIBILITY
The 4.4BSD extension of accepting arguments outside of the range of the
unsigned char type in locales with large character sets is considered
obsolete and may not be supported in future releases. The iswideogram()
or iswideogram_l() function should be used instead.
