ReadMemory -- read card's memory region

Synopsis (Unsupported service)

   #include <sys/types.h>
   #include <sys/lcs.h>
   #include <sys/lss.h>
   
   int CardServices (ReadMemory, MemoryHandle_t *mh,
                     int n2, int ReadMemoryLen,
                     ReadMemory_t *mw, rm_key_t key);

Description

ReadMemory( ) uses members of the ReadMemory(D4pccard) structure to help gain access to a desired region of memory on a Client's card. An MTD then reads the data.

Arguments

mh: Pointer to a MemoryHandle(D4pccard) structure.
n2: buffer into which the data will be read.
ReadMemoryLen: Length of the ReadMemory(D4pccard) structure.
mw: pointer to the ReadMemory(D4pccard) structure that describes the system memory buffer that will receive the data from the card.
key: Resource manager key.

Return values

UNSUPPORTED_SERVICE: Service not currently supported.

Usage

MemoryHandle_t must have been previously returned by the OpenMemory(D3pccard) service.

The data structure of ReadMemory is given as follows:
