.SH DESCRIPTION
The
.ft B
mdraw_glyph_list()
.ft R
function computes information about glyphs corresponding to the text between
.ft B
from
.ft R
and
.ft B
to
.ft R
of M-text
.ft B
mt
.ft R
when it is drawn on a window of frame
.ft B
frame
.ft R
using the
.ft B
mdraw_text_with_control()
.ft R
function with the drawing control object
.ft B
control\fP.
.ft R
.ft B
glyphs
.ft R
is an array of objects to store the information, and
.ft B
array_size
.ft R
is the array size.
.PP
If
.ft B
array_size
.ft R
is large enough to cover all glyphs, it stores the number of actually filled elements in the place pointed by
.ft B
num_glyphs_return\fP,
.ft R
and returns 0.
.PP
Otherwise, it stores the required array size in the place pointed by
.ft B
num_glyphs_return\fP,
.ft R
and returns -1.
