osPfsReSizeFile
This function has been omitted beginning from Version OS 2.0I.
Syntax
#include <ultra64.h>
s32 osPfsReSizeFile(OSPfs *pfs, u16 company_code, u32 game_code,
u8 *game_name, u8 *ext_name, int length);
Explanation
osPfsReSizeFile increases and decreases the size of existing game notes. However, since attempting to change the number of pages during a game may confuse the game user, use of this function should be minimized.
Information specified for game notes is the company code (company_code), game code (game_code), game name (game_name), extension (ext_name), and the new note size (length). Although the size is expressed in bytes, it must actually be allocated as a number of pages, so it should be specified as a multiple of 256.
When game note size is decreased, the area that is removed can no longer be read. When the size is increased, the area that is added is set to 0x00.
If the function is successful, 0 is returned; otherwise, the following error codes are returned.
PFS_ERR_NOPACK
A Controller Pak has not been inserted in the specified controller. Or some type of PIf error was issued for a reason such as the controller not being inserted. Means such as using osContStartQuery(3P) and osContGetQuery(3P) should be employed to check which of these is the cause.
PFS_ERR_NEW_PACK
A different Controller Pak has been inserted. If this Controller Pak is to be used, call osPfsInitPak (3P) to initialize it.
PFS_ERR_INCONSISTENT
An abnormality is present in the file system management area. This error usually does not occur because osPfsChecker (3P) is called internally when osPfsInitPak (3P) is used to initialize the file system. If this error is returned, the connection may be bad or an abnormality may be present in the Controller Pak itself.
PFS_ERR_CONTRFAIL
Data transmission to or from the controller failed. When a transmission error occurs, the function internally makes up to 3 more transmission attempts. Thus, this error is not often issued. If the error is returned, the controller may not be properly connected, or an abnormality may exist in the Controller Pak or controller connector.
PFS_ERR_INVALID
An incorrect argument was specified for a parameter when the function was called, the specified game note does not exist, or the function Pfs was called without initialization by osPfsInitPak (3P). This error usually is not returned.
