   capng_setpid    ( 3 )

---

---

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.
