set_poll_func
Description:
Sets the function to use to handle polling of file descriptors.
It will be used instead of the [`poll()`](man:poll(2)) system call (or GLib’s replacement function, which is used where `poll()` isn’t available).
This function could possibly be used to integrate the GLib event loop with an external event loop.
Parameters:
| this |
a main context (if `NULL`, the global-default main context will be used) |
| func |
the function to call to poll all file descriptors |
