Function Documentation

◆ fs_ramdisk_attach()

int fs_ramdisk_attach	(	const char *	fn,
		void *	obj,
		size_t	size )

Attach a block of memory as a file in the ramdisk.

This function takes a block of memory and associates it with a file on the ramdisk. This memory should be allocated with malloc(), as an unlink() of the file will call free on the block of memory. The ramdisk then effectively takes control of the block, and is responsible for it at that point.

Parameters

fn	The name to give the new file
obj	The block of memory to associate
size	The size of the block of memory

Return values

0	On success
-1	On failure

◆ fs_ramdisk_detach()

int fs_ramdisk_detach	(	const char *	fn,
		void **	obj,
		size_t *	size )

Detach a file from the ramdisk.

This function retrieves the block of memory associated with the file, removing it from the ramdisk. You are responsible for freeing obj when you are done with it.
