capng_setpid - set working pid
#include <cap-ng.h>
void capng_setpid(int pid);
capng_pid sets the working pid for capabilities operations. This is useful if
you want to get the capabilities of a different process.
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.
None.
