DESCRIPTION
|
| 48 |
|
|
<<wctrans>> is a function which takes a string <[c]> and gives back
|
| 49 |
|
|
the appropriate wctrans_t type value associated with the string,
|
| 50 |
|
|
if one exists. The following values are guaranteed to be recognized:
|
| 51 |
|
|
"tolower" and "toupper".
|
| 52 |
|
|
|
| 53 |
|
|
RETURNS
|
| 54 |
|
|
<<wctrans>> returns 0 and sets <<errno>> to <<EINVAL>> if the
|
| 55 |
|
|
given name is invalid. Otherwise, it returns a valid non-zero wctrans_t
|
| 56 |
|
|
value.
|
| 57 |
|
|
|
| 58 |
|
|
PORTABILITY
|
| 59 |
|
|
<<wctrans>> is C99.
|
| 60 |
|
|
|
| 61 |
|
|
No supporting OS subroutines are required.
