GRgetlutinfo/mgglinf

intn GRgetlutinfo(int32 pal_id, int32 *ncomp, int32 *data_type, int32 *interlace_mode, int32 *num_entries)

pal_id	IN:	Palette identifier returned by GRgetlutid
ncomp	OUT:	Number of components in the palette
data_type	OUT:	Data type of the palette
interlace_mode	OUT:	Interlace mode of the stored palette data
num_entries	OUT:	Number of color lookup table entries in the palette

Purpose	Retrieves information about a palette.
Return value	Returns SUCCEED (or 0) if successful and FAIL (or -1) otherwise.
Description	GRgetlutinfo retrieves the number of pixel components, data type, interlace mode, and number of color lookup table entries of the palette identified by the parameter pal_id. These values are stored in the parameters ncomp, data_type, interlace_mode, and num_entries, respectively. In C if the value of any of the output parameters are set to NULL, the corresponding information will not be retrieved.

FORTRAN	integer function mgglinf(pal_id, ncomp, data_type, interlace_mode, num_entries)
	integer pal_id, ncomp, data_type, interlace_mode, num_entries
