GPR_$INQ_TEXT16_EXTENT GPR Calls GPR_$INQ_TEXT16_EXTENT
NAME
gpr_$inq_text16_extent - returns the extent of an array of 16-bit charac-
ters.
FORMAT
gpr_$inq_text16_extent (t_array, t_arrayl, size, status)
DESCRIPTION
This routine returns the x- and y-offsets that the specified array of
16-bit characters would span if written with gpr_$text16.
Input Parameters
t_array
The array of 16-bit characters to inquire about, in
gpr_$16bit_character_array_t format. This is an array of unsigned
2-byte integers.
t_arrayl
The number of 16-bit characters in the array. This is a 2-byte
integer.
Output Parameters
size The width and height the written character array will occupy, in
gpr_$offset_t format. This data type is 4 bytes long.
status
Completion status, in status_$t format.
NOTES
When the text path is gpr_$right or gpr_$left, the width is the x-offset.
When the text path is gpr_$up or gpr_$down, the width is the y-offset.
To change the direction of text, use gpr_$set_text_path.
