WCSXFRM(3) FreeBSD Library Functions Manual WCSXFRM(3) 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. FreeBSD 14.1-RELEASE-p8 October 13, 2006 FreeBSD 14.1-RELEASE-p8
