pccard_raw_read()
Read the raw CIS data from the PC Card
Synopsis:
#include <sys/pccard.h>
ssize_t pccard_raw_read( pccard_t handle,
int socket,
int type,
unsigned addr,
ssize_t len,
void* buf );
Arguments:
- handle
- The handle returned by pccard_attach().
- socket
- Contains both the socket number as well as the function within the socket. This is achieved by shifting the function number left 8 bits and ORing it with the socket number. The socket number is zero-based.
- type
- The type of memory that you want to read. Valid values are:
- _PCCARD_MEMTYPE_COMMON
- _PCCARD_MEMTYPE_ATTRIBUTE
- addr
- The memory address that you want to read from the CIS.
- len
- The size of the memory that you want to read.
- buf
- A pointer to a buffer where the function can store the information that it reads from the PC Card.
Library:
libpccard
Use the -l pccard option to qcc to link against this library.
