CONTENTS

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
isalpha_l(int c, locale_t loc);

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.
