strxfrm - string transformation
size_t strxfrm(char *restrict dest, const char *restrict src,
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 bytes of the
transformed string are placed in dest. The transformation is based on
the program's current locale for category LC_COLLATE. (See

If the value returned is n or more, the contents of dest are
