установить рабочий pid (set working pid)
Имя (Name)
capng_setpid - set working pid
Синопсис (Synopsis)
#include <cap-ng.h>
void capng_setpid(int pid);
Описание (Description)
capng_pid sets the working pid for capabilities operations. This
is useful if you want to get the capabilities of a different
process.
Примечание (Note)
If your process calls fork , then the child process will still
have the pid of the parent process stored in libcap-ng's internal
data. It is disallowed to do any kind of setcap operations
because you would be crossing process boundaries. To correct
this, if your program links against pthreads, then libcap-ng will
use the pthread_atfork function (as a weak symbol) to reset the
pid information to the new process automatically. You are not
required to link against pthreads. You can call capng_setpid and
adjust the stored pid manually.
Возвращаемое значение (Return value)
