NAME

strxfrm – transform a string under locale

CONTENTS

LIBRARY

Standard C Library (libc, -lc)

SYNOPSIS

#include <string.h>

size_t
strxfrm(char * restrict dst, const char * restrict src, size_t n);

size_t
strxfrm_l(char * restrict dst, const char *restrict src, size_t n, locale_t loc);

DESCRIPTION

The strxfrm() function transforms a null-terminated string pointed to by src according to the current locale collation if any, then copies the transformed string into dst. Not more than n characters are copied into dst, including the terminating null character added. If n is set to 0 (it helps to determine an actual size needed for transformation), dst is permitted to be a NULL pointer.

Comparing two strings using strcmp() after strxfrm() is equal to comparing two original strings with strcoll().

strxfrm_l() does the same, however takes an explicit locale rather than the global locale.

RETURN VALUES

Upon successful completion, strxfrm() and strxfrm_l() return the length of the transformed string not including the terminating null character. If this value is n or more, the contents of dst are indeterminate.

SEE ALSO

setlocale(3), strcmp(3), strcoll(3), wcsxfrm(3)

STANDARDS

The strxfrm() function conforms to ISO/IEC 9899:1990 ("ISO C90"). The strxfrm_l() function conforms to IEEE Std 1003.1-2008 ("POSIX.1").
