[patch] add intptr uintptr to (system foreign) |
|
Date: |
Tue, 4 Jul 2017 16:38:37 -0700 |
I submit this patch for adding intptr and uintptr to (system foreign).
This is with reference to guile-2.2.2 and changes libguile/foreign.c and
module/system/foreign.scm.
After application, I was albe to get guile-2.2.2 to complete “make” and “make
check”.
No specific tests for this patch have been performed.
Rationale: I am working on a FFI helper which uses scheme-bytestructure (see
GitHub.com) and that package includes these types.

I updated api-foreign.texi accordingly, added a commit log, and
committed to the ‘stable-2.2’ branch.
Thank you!
