source: functions.c @ 801b7ac

barnowl_perlaimdebianrelease-1.4release-1.5release-1.6release-1.7release-1.8release-1.9
Last change on this file since 801b7ac was 801b7ac, checked in by Alejandro R. Sedeño <asedeno@mit.edu>, 14 years ago
functions.c: tweak owl_function_calculate_topmsg_normal to not suck as much. This resolves the delay in jumping from the first message to the last message. fmtext.c: get rid of a debug message and an unused variable. view.c: Convert another linear search to binary search.
