strxfrm - string transformation
The strxfrm() function transforms the
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 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
more, the contents of
dest are indeterminate.
