Function Documentation

romfsMountFromCurrentProcess()

Result romfsMountFromCurrentProcess

(

const char *

name

)

Mounts RomFS using the current process host program RomFS.

Parameters

name	Device mount name.

romfsMountFromFile()

Result romfsMountFromFile	(	Handle	fd,
		u32	offset,
		const char *	name
	)

Mounts RomFS from an open file.

Parameters

fd	FSFILE handle of the RomFS image.
offset	Offset of the RomFS within the file.
name	Device mount name.

romfsMountFromTitle()

Result romfsMountFromTitle	(	u64	tid,
		FS_MediaType	mediatype,
		const char *	name
	)

Mounts RomFS from the specified title.

Parameters

tid	Title ID
mediatype	Mediatype
name	Device mount name.

romfsMountSelf()

Result romfsMountSelf

(

const char *

name

)

Mounts the Application's RomFS.

Parameters

name	Device mount name.

Remarks

This function is intended to be used to access one's own RomFS. If the application is running as 3DSX, it mounts the embedded RomFS section inside the 3DSX. If on the other hand it's an NCCH, it behaves identically to romfsMountFromCurrentProcess.
