int alt_read_flash( alt_flash_fd* fd,

int offset,

void* dest_addr,

int length );

In the "Using Flash Devices" section of the Nios II SW Developers Handbook.

"A call to alt_read_flash() reads from the flash device with the handle fd,

offset bytes from the beginning of the flash device. The function writes the data to

location pointed to by dest_addr, and the amount of data read is length. For most

flash devices, you can access the contents as standard memory, making it unnecessary

to use alt_read_flash()."
