strxfrm - string transformation
size_t strxfrm(char *dest, const char *src, size_t n);
The strxfrm() function transforms the src string into a form such that
the result of strcmp(3) on two strings that have been transformed with
strxfrm() is the same as the result of strcoll(3) on the two strings
before their transformation. The first n characters of the transformed
string are placed in dest. The transformation is based on the
program’s current locale for category LC_COLLATE. (See setlocale(3)).
The strxfrm() function returns the number of bytes required to store
the transformed string in dest excluding the terminating '\0'
character. If the value returned is n or more, the contents of dest

In the "POSIX" or "C" locales strxfrm() is equivalent to copying the
string with strncpy(3).
