NANDOpenAsync

Syntax

#include <revolution/nand.h>

#define NAND_ACCESS_READ       0x01
#define NAND_ACCESS_WRITE      0x02
#define NAND_ACCESS_RW         (NAND_ACCESS_READ | NAND_ACCESS_WRITE)

typedef void (*NANDCallback)( s32 result, NANDCommandBlock *block );

s32 NANDOpenAsync( const char *path, NANDFileInfo *info, u8 accType, NANDCallback cb, NANDCommandBlock *block );

Arguments

path	File name to open.
info	Pointer to a NANDFileInfo structure.
accType	Access type. Specifies either NAND_ACCESS_READ, NAND_ACCESS_WRITE or NAND_ACCESS_RW.
cb	Callback function to call when this function completes processing.
block	Command block structure to be passed to the callback function.

Return Values

The result codes that may be returned by NANDOpenAsync are listed below. Returns NAND_RESULT_OK when the request begins normally.

NAND_RESULT_OK
NAND_RESULT_ACCESS
NAND_RESULT_ALLOC_FAILED
NAND_RESULT_BUSY
NAND_RESULT_INVALID
NAND_RESULT_FATAL_ERROR


The result codes that may be passed to the callback function are listed below.

NAND_RESULT_OK
NAND_RESULT_ACCESS
NAND_RESULT_INVALID
NAND_RESULT_MAXFD
NAND_RESULT_NOEXISTS
NAND_RESULT_UNKNOWN
NAND_RESULT_FATAL_ERROR


Description

Asynchronously opens a file. Proper access rights are required to open a file. You can't open files if you don't have permission to access those files. NAND_RESULT_BUSY is returned and this function call is denied when the queue for accepting requests inside the library is full.
