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.
