osPfsNumFiles
Format#include <ultra64.h>
s32 osPfsNumFiles(OSPfs *pfs, s32 *max_files, s32 *files_used);
What This Function Does
It acquires the maximum note number and the number of notes used in the Controller Pak. When called, this function returns the number of notes used to the location pointed to by the files_used argument, and it returns the total number of notes to the location pointed to by the max_files argument.
If the function is successful, it returns a 0 as the return value. If an error occurs, one of 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, so this error is rarely seen. If it does occur, 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 the osPfsChecker function is called internally when you initialize the file system with 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 being initialized by using osPfsInitPak. Therefore, usually this error is not returned.
