Method Summary

Modifier and Type	Method	Description
void	run(Pid pid, int waitStatus)	Prototype of a GChildWatchSource callback, called when a child process has exited.
default MemorySegment	toCallback(Arena arena)	Creates a native function pointer to the upcall(int, int, MemorySegment) method.
default void	upcall(int pid, int waitStatus, MemorySegment userData)	The upcall method is called from native code.

Method Details

run

void run(Pid pid,
 int waitStatus)

Prototype of a GChildWatchSource callback, called when a child process has exited.

To interpret waitStatus, see the documentation for GLib.spawnCheckWaitStatus(int). In particular, on Unix platforms, note that it is usually not equal to the integer passed to exit() or returned from main().

Parameters:

pid - the process id of the child process

waitStatus - Status information about the child process, encoded in a platform-specific manner

upcall

default void upcall(int pid,
 int waitStatus,
 MemorySegment userData)

The upcall method is called from native code. The parameters are marshaled and run(Pid, int) is executed.

toCallback

default MemorySegment toCallback(Arena arena)

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

Specified by:

toCallback in interface FunctionPointer

Parameters:

arena - the arena in which the function pointer is allocated

Returns:

the native function pointer
