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 );

Library:

libpccard

Description:

The pccard_raw_read() function returns the raw CIS (Card Information Structure) data from the PC Card. The parameters are:

handle

Obtained from a previous call to 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

Specifies what memory is to be read. Valid values are:

• _PCCARD_MEMTYPE_COMMON -- Common
• _PCCARD_MEMTYPE_ATTRIBUTE -- Attribute

addr

Specifies what memory address is to be read from CIS for size len into the buffer pointed to by buf.

Returns:

A positive integer

Success. The length read is returned.

-1

An error occurred (errno is set).

Errors:

EBADF

Invalid handle parameter.

ENODEV

Invalid socket parameter.

Examples:

See pccard_arm().

Classification:
