GRendaccess/mgendac

intn GRendaccess(int32 ri_id)

ri_id IN:

Raster image identifier returned by GRcreate or GRselect

Purpose

Terminates access to a raster image.

Return value

Returns SUCCEED (or 0) if successful and FAIL (or -1) otherwise.

Description

GRendaccess terminates access to the raster image identified by the parameter ri_id and disposes of the raster image identifier. This access is initiated by either GRselect or GRcreate. There must be a call to GRendaccess for each call to GRselect or GRcreate; failing to provide this will result in loss of data. Attempts to access a raster image identifier disposed of by GRendaccess will result in an error condition.
