Revision 1.17, Wed Jun 14 14:10:50 2006 UTC (18 years ago) by joris
Branch: MAIN
Changes since 1.16: +2 -1 lines
add cvs_buf_load_fd() which does the same as cvs_buf_load()
except it takes a decriptor as argument instead of a path.
modified cvs_buf_load() to open the descriptor then pass
it to cvs_buf_load_fd().
change all the calls to cvs_buf_load() that have a descriptor
open for the path to cvs_buf_load_fd() to prevent races.
