| Allegro CL version 8.2 Unrevised from 8.1 to 8.2. 8.1 version |
Arguments: stream fontmetrics
Modifies as necessary and returns the specified fontmetrics
object so it describes
the current font
of stream.
This destructive version of fontmetrics may be useful for
avoiding consing a lot of fontmetrics
objects if
frequent calls are required; this could be done by calling make-fontmetrics just
once to create a single utility fontmetrics
object, and
then passing it to nfontmetrics each time a call to
this function is needed (using the object temporarily within a single
process where re-entrancy is not an issue).
