NAME
pvm_lvgroup - Unenrolls the calling process from a named group. SYNOPSIS
C int info = pvm_lvgroup( char *group ) Fortran call pvmflvgroup( group, info ) PARAMETERS
group Character string group name of an existing group. info Integer status code returned by the routine. Values less than zero indicate an error. DESCRIPTION
The routine pvm_lvgroup unenrolls the calling process from the group named group. If there is an error info will be negative. If a process leaves a group by calling either pvm_lvgroup or pvm_exit, and later rejoins the same group, the process may be assigned a new instance number. Old instance numbers are reassigned to processes calling pvm_joingroup. EXAMPLES
C: info = pvm_lvgroup( "worker" ); Fortran: CALL PVMFLVGROUP( 'group2', INFO ) ERRORS
These error conditions can be returned by pvm_lvgroup PvmSysErr pvmd not responding. PvmBadParam giving a NULL group name. PvmNoGroup giving a non-existent group name. PvmNotInGroup asking to leave a group you are not a member of. SEE ALSO
