VFS driver for accessing romdisks binaries

Function Documentation

fs_romdisk_mount()

int fs_romdisk_mount	(	const char *	mountpoint,
		const uint8 *	img,
		int	own_buffer )

Mount a ROMFS image as a new filesystem.

This function will mount a ROMFS image that has been loaded into memory to the specified mountpoint.

Parameters

mountpoint	The directory to mount this romdisk on
img	The ROMFS image
own_buffer	If 0, you are still responsible for img, and must free it if appropriate. If non-zero, img will be freed when it is unmounted

Return values

0	On success
-1	If fs_romdisk_init not called
-2	If img is invalid
-3	If a malloc fails

fs_romdisk_unmount()

int fs_romdisk_unmount

(

const char *

mountpoint

)

Unmount a ROMFS image.

This function unmounts a ROMFS image that has been previously mounted with fs_romdisk_mount(). This function does not check for open files on the fs, so make sure that all files have been closed before calling it. If the VFS owns the buffer (own_buffer was non-zero when you called the mount function) then this function will also free the buffer.

Parameters

mountpoint

The ROMFS to unmount

Return values

0	On success
-1	On error

Error Conditions:

ENOENT - no such ROMFS was mounted
