LIBRARY

Standard C Library (libc, -lc)

SYNOPSIS

#include < ctype.h>

int
digittoint_l( int c, locale_t loc);

int
isalnum_l( int c, locale_t loc);

int

int
isascii_l( int c, locale_t loc);

int
iscntrl_l( int c, locale_t loc);

int
isdigit_l( int c, locale_t loc);

int
isgraph_l( int c, locale_t loc);

int
ishexnumber_l( int c, locale_t loc);

int
isideogram_l( int c, locale_t loc);

int
islower_l( int c, locale_t loc);

int
isnumber_l( int c, locale_t loc);

int
isphonogram_l( int c, locale_t loc);

int
isspecial_l( int c, locale_t loc);

int
isprint_l( int c, locale_t loc);

int
ispunct_l( int c, locale_t loc);

int
isrune_l( int c, locale_t loc);

int
isspace_l( int c, locale_t loc);

int
isupper_l( int c, locale_t loc);

int
isxdigit_l( int c, locale_t loc);

int
tolower_l( int c, locale_t loc);

int
toupper_l( int c, locale_t loc);

DESCRIPTION

The above functions perform character tests and conversions on the integer c in the locale loc. They behave in the same way as the versions without the _l suffix, but use the specified locale rather than the global or per-thread locale. < ctype.h>, or as true functions in the C library. See the specific manual pages for more information.
