Detailed Description

Macro Definition Documentation

MTP_MAX_STORAGES

#define MTP_MAX_STORAGES

Maximum number of storages a device may expose.

Typedef Documentation

mtp_func

typedef struct mtp_func mtp_func

One MTP function: a single instance of the class on a device.

Opaque - create one with mtp_add() and use the functions below. Distinct from the other classes' handles, so mixing them up is a compile error rather than a misread state block.

mtp_emit

typedef void(* mtp_emit) (void *ctx, const char *name)

Callback used by mtp_opts::listdir to report one directory entry.

Parameters

ctx	the opaque pointer that listdir() was handed.
name	the entry's name (a single path component, not a full path).

Function Documentation

mtp_add()

mtp_func * mtp_add	(	usbip_device *	dev,
		const mtp_opts *	opts
	)

Add an MTP interface to a device.

Parameters

dev	the device.
opts	device identity + one or more storage backends (see mtp_opts).

Returns

the new function, or NULL on error.
