Method Summary

Modifier and Type	Method	Description
void	run(String message, @Nullable Pid @Nullable [] processes, @Nullable String @Nullable [] choices)	Emitted when one or more processes are blocking an operation e.g.
default MemorySegment	toCallback(Arena arena)	Creates a native function pointer to the upcall(MemorySegment, MemorySegment, MemorySegment, MemorySegment) method.
default void	upcall(MemorySegment sourceMountOperation, MemorySegment message, MemorySegment processes, MemorySegment choices)	The upcall method is called from native code.

Method Details

run

void run(String message,
 @Nullable Pid @Nullable [] processes,
 @Nullable String @Nullable [] choices)

Emitted when one or more processes are blocking an operation e.g. unmounting/ejecting a GMount or stopping a GDrive.

Note that this signal may be emitted several times to update the list of blocking processes as processes close files. The application should only respond with g_mount_operation_reply() to the latest signal (setting GMountOperation:choice to the choice the user made).

If the message contains a line break, the first line should be presented as a heading. For example, it may be used as the primary text in a GtkMessageDialog.

Since:

2.22

upcall

default void upcall(MemorySegment sourceMountOperation,
 MemorySegment message,
 MemorySegment processes,
 MemorySegment choices)

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

toCallback

default MemorySegment toCallback(Arena arena)

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

Specified by:

toCallback in interface FunctionPointer

Parameters:

arena - the arena in which the function pointer is allocated

Returns:

the native function pointer
