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

s32 NANDCreateAsync( const char *filename, u8 perm, u8 attr, NANDCallback cb, NANDCommandBlock *block );

Arguments

filename Specifies the file name.

perm File permissions. Specified by taking the logical sum of NAND_PERM_*.

attr Specifies the file attributes.

cb Callback function to call when this function completes processing.

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

*`filename`*	Specifies the file name.
*`perm`*	File permissions. Specified by taking the logical sum of `NAND_PERM_*`.
*`attr`*	Specifies the file attributes.
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 NANDCreateAsync 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_CORRUPT NAND_RESULT_EXISTS NAND_RESULT_INVALID NAND_RESULT_MAXFILES NAND_RESULT_NOEXISTS NAND_RESULT_UNKNOWN NAND_RESULT_FATAL_ERROR

Description

Asynchronously creates a new file. The specified permissions and attributes are given to the file. However, the file must be granted at least the NAND_PERM_OWNER_READ permission. If the NAND_PERM_OWNER_READ permission is not granted, the function will return NAND_RESULT_INVALID. NAND_RESULT_BUSY is returned and this function call is denied when the queue for accepting requests inside the library is full.

This function updates the FAT of the Wii console NAND memory.
