osPfsFileState
Format#include <ultra64.h>
s32 osPfsFileState(OSPfs *pfs, s32 file_no, OSPfsState *state);
What This Function Does
It obtains the specified game note information. To specify a game note, use the note number file_no (file descriptor) argument. To retrieve specific game note information, it is necessary to obtain the note number by calling osPfsFindFile, before calling this function. Also, to retrieve all game note information in a Controller Pak, assign 0 to 15 to the file number (file_no) and call osPfsFileState 16 times.
The OSPfs handle must be the handle returned from osPfsInitPak. See the osPfsInitPak page for information on how to create this handle.
The game note information is stored in the OSPfsState structure specified by the pointer state argument. The following is the definition of that structure:
typedef struct {
u32 file_size; /*Note Size*/
u32 game_code; /*Game Code*/
u16 company_code; /*Company Code*/
char ext_name[4]; /*Note Extension*/
char game_name[16]; /*Note Name*/
}
If this function is called successfully, a 0 is returned. If an error occurs, one of the following error codes is returned:
- PFS_ERR_NOPACK - Some type of PIF error has occurred. Either the Controller Pak is not inserted into the specified Controller or the Controller is not properly connected. To determine which is the case, use osContStartQuery or osContGetQuery.
- PFS_ERR_NEW_PACK - A different Controller Pak has been inserted. To use the inserted Controller Pak, initialize it by calling osPfsInitPak.
- PFS_ERR_CONTRFAIL - Data transfer to or from the Controller has failed. If a transfer error occurs, up to three tries will be done internally. Therefore, it is rather rare to see this error. If this error has returned, it is possible that either the Controller is not connected properly, or the Controller Pak or Controller Socket is damaged.
- PFS_ERR_INCONSISTENT - There is a problem in the file system's management area. Usually this error does not occur because osPfsChecker is called internally when you initialize the file system by calling osPfsInitPak. If this error is returned, either the Controller Pak is not connected properly, or the Controller Pak itself is damaged.
- PFS_ERR_INVALID - If this error is returned, an incorrect argument was specified when this function was called, the specified game note does not exist, or the Pfs function has been called without first being initialized by calling osPfsInitPak. Therefore, usually this error is not returned.
