cpusetDetachAll(3x)                                        cpusetDetachAll(3x)


NAME
     cpusetDetachAll - detaches all threads from a cpuset

SYNOPSIS
     #include <cpuset.h>

     int cpusetDetachAll(char *qname);

DESCRIPTION
     The cpusetDetachAll function is used to detach all threads currently
     attached to the specified cpuset.  Only a process running with root user
     ID can successfully execute cpusetDetachAll.

     The qname argument is the name of the cpuset that the operation will be
     performed upon.

EXAMPLES
     This example detaches all threads from the cpuset queue named mpi_set.

               char *qname = "mpi_set";

               /* Attach to cpuset, if error - print error & exit */
               if (!cpusetDetachAll(qname)) {
                   perror("cpusetDetachAll");
                   exit(1);
               }


NOTES
     cpusetDetachAll 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
     cpuset(1), cpusetAttach(3x), cpuset(5).

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