In any case the slurpfile resizable buffer doesn't really work :( slurpfile only resizes a buffer if it's NULL but this is the case only at the first call for a metric. char *bp=NULL; slurpfile(file, &bp, 32); ...next polling interval... /* the buffer isn't resibale any more since it isn't NULL */ slurpfile(file, &bp, 32); Kostas ------------------------------------------------------------------------------ Free Software Download: Index, Search & Analyze Logs and other IT data in Real-Time with Splunk.
