strxfrm(3) [freebsd man page]

STRXFRM(3)						   BSD Library Functions Manual 						STRXFRM(3)

NAME
strxfrm -- transform a string under locale 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 charac- ter. 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''). BSD

NAME
wcsxfrm -- transform a wide string under locale LIBRARY
Standard C Library (libc, -lc) SYNOPSIS
#include <wchar.h> size_t wcsxfrm(wchar_t * restrict dst, const wchar_t * restrict src, size_t n); DESCRIPTION
The wcsxfrm() function transforms a nul-terminated wide-character string pointed to by src according to the current locale collation order then copies the transformed string into dst. No more than n wide characters are copied into dst, including the terminating nul 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 wcscmp() after wcsxfrm() is equivalent to comparing two original strings with wcscoll(). RETURN VALUES
Upon successful completion, wcsxfrm() returns the length of the transformed string not including the terminating nul character. If this value is n or more, the contents of dst are indeterminate. SEE ALSO
setlocale(3), strxfrm(3), wcscmp(3), wcscoll(3) STANDARDS
The wcsxfrm() function conforms to ISO/IEC 9899:1999 (``ISO C99''). BUGS
The current implementation of wcsxfrm() function disregards LC_COLLATE locales, and falls back to using the wcsncpy() function. BSD
