|

.Ft size_t
|
|
.Fn strxfrm "char *dst" "const char *src" "size_t n"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Fn strxfrm
|
|
function transforms a null-terminated string pointed to by
|
|
.Fa src
|
|
according to the current locale collation if any,
|
|
then copies not more than
|
|
.Fa n-1
|
|
characters of the resulting string into
|
|
.Fa dst ,
|
|
terminating it with a null character and then returns the resulting length.
|
|
Comparing two strings using
|
|
.Fn strcmp
|
|
after
|
|
.Fn strxfrm
|
|
is equal to comparing
|
|
two original strings with
|
|
.Fn strcoll .
|
|
.Sh BUGS
|
|
Sometimes the behavior of this function is unpredictable.
