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.
