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 str‐
cmp(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 bytes of the
transformed string are placed in dest. The transformation is based on the program's cur‐
rent 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 null byte ('\0'). If the value returned is n or
more, the contents of dest are indeterminate.

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