void exec_i3_utility | ( | char * | name, |
char * | argv[] ) |
exec()s an i3 utility, for example the config file migration script or i3-nagbar.
This function first searches $PATH for the given utility named, then falls back to the dirname() of the i3 executable path and then falls back to the dirname() of the target of /proc/self/exe (on linux).
This function should be called after fork()ing.
The first argument of the given argv vector will be overwritten with the executable name, so pass NULL.
If the utility cannot be found in any of these locations, it exits with return code 2.

void kill_nagbar | ( | pid_t | nagbar_pid, |
bool | wait_for_it ) |
Kills the i3-nagbar process, if nagbar_pid != -1.
If wait_for_it is set (restarting i3), this function will waitpid(), otherwise, ev is assumed to handle it (reloading).

bool layout_from_name | ( | const char * | layout_str, |

Set 'out' to the layout_t value for the given layout.
The function returns true on success or false if the passed string is not a valid layout name.
