+/*
+ * 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
+ *
