Fix libio/bug-ungetwc1.c warning.
|
|
|
00db10 |
|
|
|
00db10 |
This patch fixes a warning "variable 'wc' set but not used" in
|
|
|
00db10 |
libio/bug-ungetwc1.c.
|
|
|
00db10 |
|
|
|
00db10 |
The test didn't verify much about the results of the functions it
|
|
|
00db10 |
called. This patch makes it check the result of getwc (thereby fixing
|
|
|
00db10 |
the warning), check end of file does not arrive too late in the getwc
|
|
|
00db10 |
loop, and check EOF is no longer set after ungetwc.
|
|
|
00db10 |
|
|
|
00db10 |
Tested for x86_64.

* libio/bug-ungetwc1.c (do_test): Verify results of getwc and
|
|
|
00db10 |
feof.
