Subject: [PATCH 5/5] lib: set errno when buf points to NULL in
|
|
common.c:pqos_read()
|
|
|
|
There is little need for the check, as the first read() call is supposed
|
|
to fail with EFAULT in case buf is NULL, but if this check is done,
|
|
it would be nice if it matches the error code the call it wraps.
