.Sh SYNOPSIS
|
||
|
|
.In string.h
|
||
|
|
.Ft size_t
|
||
|
|
.Fn strxfrm "char * restrict dst" "const char * restrict src" "size_t n"
|
||
|
|
.Sh DESCRIPTION
|
||
|
|
The idea of
|
||
|
|
.Fn strxfrm
|
||
|
|
is to
|
||
|
|
.Dq un-localize
|
||
|
|
a string: the function transforms
|
||
|
|
.Ar src ,
|
||
|
|
storing the result in
|
||
|
|
.Ar dst ,
|
||
|
|
such that
|
||
|
|
.Xr strcmp 3
|
||
|
|
on transformed strings returns what
|
||
|
|
.Xr strcoll 3
|
||
|
|
on the original untransformed strings would return.

.Sh STANDARDS
|
||
|
|
The
|
||
|
|
.Fn strxfrm
|
||
|
|
function
|
||
|
|
conforms to
|
||
|
|
.St -ansiC .
|
||
|
|
.Sh BUGS
|
||
|
|
Since locales are not fully implemented on
|
||
|
|
.Nx ,
|
||
|
|
.Fn strxfrm
|
||
|
|
just returns a copy of the original string.
