NAME

       capng_setpid - set working pid

SYNOPSIS

       #include <cap-ng.h>

       void capng_setpid(int pid);

DESCRIPTION

       capng_pid  sets the working pid for capabilities operations. This is useful if you want to
       get the capabilities of a different process.

NOTES

       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.

RETURN VALUE

       None.
