<p><strong>Description</strong><br>
|
||
|
|
This function transforms the string pointed to by <var>s2</var> and
|
||
|
|
places the resulting string into the array pointed to by
|
||
|
|
<var>s1</var>. The transformation is such that if the <code>strcmp</code>
|
||
|
|
function is applied to the two transformed strings, it returns
|
||
|
|
a value greater than, equal to, or less than zero,
|
||
|
|
correspoinding to the result of a <code>strcoll</code> function applied
|
||
|
|
to the same two original strings.
|
||
|
|
</p>
|
||
|
|
<p>No more than <var>n</var> characters are placed into the resulting
|
||
|
|
array pointed to by <var>s1</var>, including the terminating null
|
||
|
|
character. If <var>n</var> is zero, <var>s1</var> may be a null pointer. If
|
||
|
|
copying takes place between objects that overlap, the behavior
|
||
|
|
is undefined.
|
||
|
|
</p>
|
||
|
|
<p>(NOT Cygwin:) The current implementation of <code>strxfrm</code> simply copies
|
||
|
|
the input and does not support any language-specific transformations.
|
||
|
|
</p>
|
||
|
|
<br>
|
||
|
|
<p><strong>Returns</strong><br>
|
||
|
|
The <code>strxfrm</code> function returns the length of the transformed string
|
||
|
|
(not including the terminating null character). If the value returned
|
||
|
|
is <var>n</var> or more, the contents of the array pointed to by
|
||
|
|
<var>s1</var> are indeterminate.
|
||
|
|
</p>
|
||
|
|
<br>
|
||
|
|
<p><strong>Portability</strong><br>
|
||
|
|
<code>strxfrm</code> is ANSI C.
|
||
|
|
</p>
|
||
|
|
<p><code>strxfrm</code> requires no supporting OS subroutines.
|
||
|
