8 | SYNOPSIS |
---|
9 | #include <wchar.h> |
---|
10 | int wcsxfrm(wchar_t *__restrict <[stra]>, |
---|
11 | const wchar_t *__restrict <[strb]>, size_t <[n]>); |
---|
12 | |
---|
13 | DESCRIPTION |
---|
14 | <<wcsxfrm>> transforms the wide-character string pointed to by |
---|
15 | <[strb]> to the wide-character string pointed to by <[stra]>, |
---|
16 | Comparing two transformed wide strings with <<wcscmp>> should return |
---|
17 | the same result as comparing the original strings with <<wcscoll>>. |
---|
18 | No more than <[n]> wide characters are transformed, including the |
---|
19 | trailing null character. |
---|
20 | |
---|
21 | If <[n]> is 0, <[stra]> may be a NULL pointer. |
---|
22 | |
---|
23 | (NOT Cygwin:) The current implementation of <<wcsxfrm>> simply uses |
---|
24 | <<wcslcpy>> and does not support any language-specific transformations. |
---|
25 | |
---|
26 | RETURNS |
---|
27 | <<wcsxfrm>> returns the length of the transformed wide character |
---|
28 | string. if the return value is greater or equal to <[n]>, the |
---|
29 | content of <[stra]> is undefined. |
---|
30 | |
---|
31 | PORTABILITY |
---|
32 | <<wcsxfrm>> is ISO/IEC 9899/AMD1:1995 (ISO C). |
