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.
