LIBRARY SYNOPSIS DESCRIPTION SEE ALSO STANDARDS HISTORY

Standard C Library (libc, -lc)

#include <stdio.h>

#include <xlocale.h>

int
printf_l(locale_t loc, const char * restrict format, ...);

int
asprintf_l(char **ret, locale_t loc, const char * format, ...);

int
fprintf_l(FILE * restrict stream, locale_t loc, const char * restrict format, ...);

int
snprintf_l(char * restrict str, size_t size, locale_t loc, const char * restrict format, ...);

int
sprintf_l(char * restrict str, locale_t loc, const char * restrict format, ...);

int
vasprintf_l(char **ret, locale_t loc, const char *format, va_list ap);

int
vfprintf_l(FILE * restrict stream, locale_t loc, const char * restrict format, va_list ap);

int
vprintf_l(locale_t loc, const char * restrict format, va_list ap);

int
vsnprintf_l(char * restrict str, size_t size, locale_t loc, const char * restrict format, va_list ap);

int
vsprintf_l(char * restrict str, locale_t loc, const char * restrict format, va_list ap);

The above functions are used to convert formatted output 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. See the specific manual pages for more information.

These functions do not conform to any specific standard so they should be considered as non-portable local extensions.

These functions first appeared in Darwin and were first implemented in FreeBSD 9.1 .
