- * 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. If NULL
- * the return value of the child will be the function's return value.
- * 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)
- * log_target: Specify where to log the output of the child, either LOG_NONE,
- * LOG_ALOG (for the Android system log), LOG_KLOG (for the kernel
- * log), or LOG_FILE (and you need to specify a pathname in the
- * file_path argument, otherwise pass NULL). These are bit fields,
- * and can be OR'ed together to log to multiple places.
- * abbreviated: If true, capture up to the first 100 lines and last 4K of
- * output from the child. The abbreviated output is not dumped to
- * the specified log until the child has exited.
- * file_path: if log_target has the LOG_FILE bit set, then this parameter
- * must be set to the pathname of the file to log to.
- *
- * Return value:
- * 0 when logwrap successfully run the child process and captured its status
- * -1 when an internal error occurred
- * -ECHILD if status is NULL and the child didn't exit properly
- * the return value of the child if it exited properly and status is NULL
