NAME    [Toc]    [Back]

     cpusetDetachPID - detach a	specific process from a	cpuset

SYNOPSIS    [Toc]    [Back]

     #include <cpuset.h>

     int cpusetDetachPID(qname,	pid);

     char *qname;

     pid_t pid;

DESCRIPTION    [Toc]    [Back]

     The cpusetDetachPID function is used to detach a specific process
     identified	by its PID from	the cpuset identified by qname.	 Every cpuset
     queue has a file that defines access permissions to the queue.  The
     execute permissions for that file will determine if a process owned by a
     specific user can detach a	process	from the cpuset	queue.

     The qname argument	is the name of the cpuset to which the specified
     process should be detached.

EXAMPLES    [Toc]    [Back]

     This example detaches the current process from a cpuset queue named
     mpi_set.

	       char *qname = "mpi_set";

	       /* Detach from cpuset, if error - print error & exit */
	       if (!cpusetDetachPID(qname, pid)) {
		   perror("cpuseDetachPID");
		   exit(1);
	       }

NOTES    [Toc]    [Back]

     cpusetDetachPID is	found in the library "libcpuset.so", and will be
     loaded if the option -lcpuset is used with	cc(1) or ld(1).

SEE ALSO    [Toc]    [Back]

     cpuset(1),	cpusetCreate(3x), cpusetAttachPID(3x), cpuset(5).

DIAGNOSTICS    [Toc]    [Back]

     If	successful, cpusetDetachPID returns a 1.  If cpusetDetachPID fails, it
     returns the value 0 and errno is set to indicate the error.  The possible
     values for	errno are the same as those used by sysmp(2).
