SHPDEALLC(3F)						      SHPDEALLC(3F)

NAME
     SHPDEALLC - Returns a memory block to the symmetric heap

SYNOPSIS
     POINTER (addr, A(1))
     INTEGER errcode, abort
     CALL SHPDEALLC(addr, errcode, abort)

DESCRIPTION
     SHPDEALLC returns a block of memory (allocated using SHPALLOC) to the
     list of available space in the symmetric heap.  To maintain symmetric
     heap consistency, all processing elements (PEs) in a program must call
     SHPDEALLC with the same value of addr; if any PEs are missing, the
     program hangs.

     The SHPDEALLC function accepts the following arguments:

     Argument	    Description
     addr	    First word address of the block to deallocate (input).
     errcode	    Error code is 0 if no error was detected; otherwise, it
		    is a negative integer code for the type of error
		    (output).
     abort	    Abort code.	 Nonzero requests abort on error; 0
		    requests an error code (input).

     Error conditions are as follows:

     Code	    Condition
     -3		    Address is outside the bounds of the symmetric heap.
     -4		    Block is already free.
     -5		    Address is not at the beginning of the block.
