size_t strxfrm (char s1, const char s2, size_t n);
strxfrm transforms the string s2 and places the resulting
string into the array s1.
The transformation is such that
if strcmp is applied to two transformed strings,
it returns a value greater than, equal to, or less than zero,
corresponding to the result of the strcoll function
applied to the same two original strings.
The transformation is based on the program's locale
for category LC_COLLATE [see
No more than n characters will be placed into the resulting
array pointed to by s1, including the terminating
If n is 0, then s1 is permitted to be a null pointer.
If copying takes place between objects that overlap,
the behavior is undefined.
strxfrm returns the length of the transformed string (not including
the terminating null character).
If the value returned is n or
more, the contents of the array s1 are indeterminate.
LC_COLLATE database for locale.
On failure, strxfrm returns (size_t) -1.
The value of the following expression is the size of the array needed to hold
the transformation of the string pointed to by s.
1 + strxfrm(NULL, s, 0);
