Subject: [PATCH] XRes: Use _XRead instead of _XRead32 for reading pid
|
|
|
bc13f0 |
|
|
|
bc13f0 |
_XRead32 requires the output variable to be a long, but
|
|
|
bc13f0 |
`ReadClientValues` feeds it client->value which is a
|
|
|
bc13f0 |
32-bit allocation.

This commit changes the code to use _XRead instead, which
|
|
|
bc13f0 |
properly handles 32-bit output variables.
