/*
|
|
* Run a command while logging its stdout and stderr
|
|
*
|
|
* WARNING: while this function is running it will clear all SIGCHLD handlers
|
|
* if you rely on SIGCHLD in the caller there is a chance zombies will be
|
|
* created if you're not calling waitpid after calling this. This function will
|
|
* log a warning when it clears SIGCHLD for processes other than the child it
|
|
* created.
|
|
*
|
|
* Arguments:
|
|
* argc: the number of elements in argv
|
|
* argv: an array of strings containing the command to be executed and its
|
|
* arguments as separate strings. argv does not need to be
|
|
* NULL-terminated
|
|
* status: the equivalent child status as populated by wait(status). This
|
|
* value is only valid when logwrap successfully completes
|
|
* ignore_int_quit: set to true if you want to completely ignore SIGINT and
|
|
* SIGQUIT while logwrap is running. This may force the end-user to
|
|
* send a signal twice to signal the caller (once for the child, and
|
|
* once for the caller)
|
|
* logwrap: when true, log messages from the child
|
|
*
|
|
* Return value:
|
|
* 0 when logwrap successfully run the child process and captured its status
|
|
* -1 when an internal error occurred
