Revision:	1.12
Committed:	Mon Apr 5 15:40:15 2004 UTC (20 years, 1 month ago) by ats
Content type:	text/plain
Branch:	MAIN
Changes since 1.11:	+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.
