default MemorySegment	toCallback(Arena arena)	Creates a native function pointer to the upcall(java.lang.foreign.MemorySegment, int, int) method.
default int	upcall(MemorySegment ufds, int nfsd, int timeout)	The upcall method is called from native code.

Method Details

run

int run(PollFD ufds,
 int nfsd,
 int timeout)

Specifies the type of function passed to g_main_context_set_poll_func(). The semantics of the function should match those of the poll() system call.

upcall

default int upcall(MemorySegment ufds,
 int nfsd,
 int timeout)

The upcall method is called from native code. The parameters are marshaled and run(org.gnome.glib.PollFD, int, int) is executed.

toCallback

default MemorySegment toCallback(Arena arena)

Creates a native function pointer to the upcall(java.lang.foreign.MemorySegment, int, int) method.

Specified by:

toCallback in interface FunctionPointer

Parameters:

arena - the function pointer will be allocated in this arena
