rad_detach_pid

rad_detach_pid(3)					     Library Functions Manual						 rad_detach_pid(3)

NAME

       rad_detach_pid - Detach a process from a Resource Affinity Domain by pid (libnuma library)

SYNOPSIS

       #include <numa.h>

       int rad_detach_pid(
	       pid_t pid );

PARAMETERS

       Specifies a process identifier (pid) to detach from a RAD set.

DESCRIPTION

       The  rad_detach_pid()  function	frees  a  process  that  has  been  bound  or  attached  to  a RAD through the functions rad_bind_pid() or
       rad_attach_pid(), respectively.	If the pid argument is NULL, the call is self-directed. That is, the function behaves as  if  the  calling
       process's pid were specified. Calling rad_detach_pid() for a process that is not attached or bound is not considered to be an error.

RETURN VALUES

       Success.  In  this case, rad_detach_pid() detaches the pid specified by pid from the RAD set.  Failure. In this case, errno is set to indi-
       cate the error.

ERRORS

       If the rad_detach_pid() function fails, errno is set to one of the following values for the reasons specified.  The  process  specified	in
       pid  does  not  exist.  The real or effective user ID of the caller does not match the real or effective user ID of the process pid, or the
       caller does not have appropriate privileges to free processes from RADs.
