# NAME

printf_l, asprintf_l, fprintf_l, snprintf_l, sprintf_l, vasprintf_l, vfprintf_l, vprintf_l, vsnprintf_l, vsprintf_l — formatted output conversion

# LIBRARY

Standard C Library (libc, -lc)

# SYNOPSIS

#include <stdio.h>
#include <locale.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, ...);
#include <stdarg.h>
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);

# DESCRIPTION

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.

# SEE ALSO

printf(3), xlocale(3)

# STANDARDS

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

# HISTORY

These functions first appeared in Darwin and were first implemented in FreeBSD 9.1 and NetBSD 7.
