GPR_$INQ_BITMAP_VIDEO_FORMAT      GPR Calls       GPR_$INQ_BITMAP_VIDEO_FORMAT


NAME
     gpr_$inq_bitmap_video_format - returns the video format for the bitmap.

FORMAT
     gpr_$inq_bitmap_video_format (bitmap, vidform, status)

DESCRIPTION
     This routine returns the video format for the specified display bitmap.

   Input Parameters
     bitmap
          The descriptor of the bitmap, in gpr_$bitmap_desc_t format.

   Output Parameters
     vidform
          A pointer to the video format, which is in gpr_$video_format_t for-
          mat.  This data type is a record in Pascal, a structure in C, or an
          array in FORTRAN.  The video format specifies which buffer will be
          displayed.

     status
          Completion status, in status_$t format.

NOTES
     The video format is set in gpr_$initialize.  The default format sets
     video_buffer to 1.

     Since the video format is associated with the window rather than the bit-
     map, any bitmap descriptor associated with a window will return the
     correct video format for that window.

     This routine only works for display bitmaps.
