Source.setCallback

Sets the callback function for a source. The callback for a source is called from the source's dispatch function.

The exact type of @func depends on the type of source; ie. you should not count on @func being called with @data as its first parameter.

See [memory management of sources][mainloop-memory-management] for details on how to handle memory management of @data.

Typically, you won't use this function. Instead use functions specific to the type of source you are using.

class Source
void
setCallback

Parameters

func GSourceFunc

a callback function

data void*

the data to pass to callback function

notify GDestroyNotify

a function to call when @data is no longer in use, or %NULL.
