WCSXFRM(3) FreeBSD Library Functions Manual WCSXFRM(3)

wcsxfrm
transform a wide string under locale

Standard C Library (libc, -lc)

#include <wchar.h>

size_t
wcsxfrm(wchar_t * restrict dst, const wchar_t * restrict src, size_t n);

The wcsxfrm() function transforms a null-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 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 wcscmp() after wcsxfrm() is equivalent to comparing two original strings with wcscoll().

Upon successful completion, wcsxfrm() returns 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.

setlocale(3), strxfrm(3), wcscmp(3), wcscoll(3)

The wcsxfrm() function conforms to ISO/IEC 9899:1999 (“ISO C99”).

The current implementation of wcsxfrm() only works in single-byte LC_CTYPE locales, and falls back to using wcsncpy() in locales with extended character sets.

Comparing two strings using wcscmp() after wcsxfrm() is not always equivalent to comparison with wcscoll(); wcsxfrm() only stores information about primary collation weights into dst, whereas wcscoll() compares characters using both primary and secondary weights.
