ANSI_SYNOPSIS
|
||
|
#include <wctype.h>
|
||
|
wctrans_t wctrans(const char *<[c]>);
|
||
|
|
||
|
TRAD_SYNOPSIS
|
||
|
#include <wctype.h>
|

|
|
||
|
DESCRIPTION
|
||
|
<<wctrans>> is a function which takes a string <[c]> and gives back
|
||
|
the appropriate wctrans_t type value associated with the string,
|
||
|
if one exists. The following values are guaranteed to be recognized:
|
||
|
"tolower" and "toupper".
|
||
|
|
||
|
RETURNS
|
||
|
<<wctrans>> returns 0 and sets <<errno>> to <<EINVAL>> if the
|
||
|
given name is invalid. Otherwise, it returns a valid non-zero wctrans_t
|
||
|
value.
|
||
|
|
||
|
PORTABILITY
|
||
|
<<wctrans>> is C99.
|
||
|
|
||
|
No supporting OS subroutines are required.
