GSIZE(3PVM) PVM Version 3.4 GSIZE(3PVM)NAME
pvm_gsize - Returns the number of members presently in the named group.
SYNOPSIS
C int size = pvm_gsize( char *group )
Fortran call pvmfgsize( group, size )
PARAMETERS
group Character string group name of an existing group.
size Integer returning the number of members presently in the group. Values less than zero indicate an error.
DESCRIPTION
The routine pvm_gsize returns the size of the group named group. If there is an error size will be negative.
Since groups can change dynamically in PVM 3.0, this routine can only guarantee to return the instantaneous size of a given group.
EXAMPLES
C:
size = pvm_gsize( "worker" );
Fortran:
CALL PVMFGSIZE( 'group2', SIZE )
ERRORS
These error conditions can be returned by pvm_gsize
PvmSysErr
pvmd was not started or has crashed.
PvmBadParam
giving an invalid group name.

LVGROUP(3PVM) PVM Version 3.4 LVGROUP(3PVM)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.

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.
# When the shell exits, append to the history file instead of overwriting it
