Changeset 609 for libcaca/trunk/cacaTweet

Timestamp:

Mar 14, 2006, 11:05:34 PM (15 years ago)

Author:

Message:

• Replaced all cucul_get_* exporters with a generic cucul_export() function.
• Got rid of static buffers; we now use cucul_free() to free exported buffers.
• Fixed light background in the ANSI exporter by adding escape sequences for most terminal emulators.

File:

• libcaca/trunk/caca/driver_network.c (modified) (13 diffs)
