wcscxfrm()

Transform one wide-character string into another, to a given length

Synopsis:

#include <wchar.h>

int wcscfrm( wchar_t * ws1,
             const wchar_t * ws2,
             size_t n );

Arguments:

ws1

The string that you want to transform.

ws2

The string that you want to place in dst.

n

The maximum number of characters to transform.

Library:

libc

Use the -l c option to qcc to link against this library. This library is usually included automatically.

Description:

The wcsxfrm() function transforms the string pointed to by ws2 to the buffer pointed to by ws1, to a maximum of n wide-characters, including the terminating null. The two strings shouldn't overlap.

A call to wcscmp() returns the same result for two strings transformed by wcsxfrm() as wcscoll() would return for the original versions of the strings.

---

This function doesn't report errors in its returns; set errno to 0, call wcsxfrm(), and then check errno again.

---

Returns:

The length of the transformed wide-character string. If this value is greater than n, the contents of ws1 are indeterminate.
