Suppress -Wcast-qual warnings in bsearch
|
||
|
|
|
||
|
|
The first cast to (void *) is redundant but should be (const void *)
|
||
|
|
anyway, because that's the type of the lvalue being assigned to.
|
||
|
|
|
||
|
|
The second cast is necessary and intentionally not const-correct, so
|
||
|
|
tell the compiler not to warn about it.
