Revision: 1.15
Committed: Mon Apr 5 15:40:15 2004 UTC (20 years, 1 month ago) by ats
Content type: text/plain
Branch: MAIN
Changes since 1.14: +3 -3 lines
Log Message:
Rename all the functions, types and enums in the API to be consistent.
Types are now of the form "sg_mem_stats"; functions of the form
"sg_get_mem_stats"; enums of the form "SG_PROCESS_STATE_RUNNING".
(The old get_proc_snapshot follows the usual calling convention now.)

Make internal functions static where possible.

Rename non-static internal functions to have an sg_ prefix so they don't
collide with those from other libraries. In particular, strlcpy and
strlcat are now called sg_strlcpy and sg_strlcat and are always
included.

Fix saidar and statgrab to use the new API.
