NANDGetLengthAsync

Syntax

#include <revolution/nand.h>

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

s32 NANDGetLengthAsync( NANDFileInfo *info, u32 *length, NANDCallback cb, NANDCommandBlock *block );

Arguments

info Pointer to a NANDFileInfo structure.

length Pointer to a u32-type variable that stores the file size.

cb Callback function to call when this function completes processing.

block Command block structure to be passed to the callback function.

info	Pointer to a `NANDFileInfo` structure.
length	Pointer to a u32-type variable that stores the file size.
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 NANDGetLengthAsync 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_UNKNOWN NAND_RESULT_FATAL_ERROR

Description

Asynchronously gets the file size. The size is given in bytes. NAND_RESULT_BUSY is returned and this function call is denied when the queue for accepting requests inside the library is full.
