◆ SCConfLogOpenGeneric()

int SCConfLogOpenGeneric ( ConfNode conf,
LogFileCtx log_ctx,
const char *  default_filename,
int  rotate 
)

open a generic output "log file", which may be a regular file or a socket

Parameters
confConfNode structure for the output section in question
log_ctxLog file context allocated by caller
default_filenameDefault name of file to open, if not specified in ConfNode
rotateRegister the file for rotation in HUP.
Return values
0on success
-1on error

◆ SCConfLogReopen()

int SCConfLogReopen ( LogFileCtx log_ctx)

Reopen a regular log file with the side-affect of truncating it.

This is useful to clear the log file and start a new one, or to re-open the file after its been moved by something external (eg. logrotate).
