Macro Definition Documentation

#define O_APPEND   256
#define O_ASYNC   O_NOWAIT

Asynchronous I/O mode, alias.

#define O_CREAT   512
#define O_EXCL   0

Obviously, O_EXCL has no effect in the PSXSDK.

#define O_NOBUF   16384

No buffering and console interrupt.

#define O_NONBLOCK   4
#define O_NOWAIT   32768

Asynchronous I/O mode.

#define O_RCOM   8192

Setup for remote command entry.

Real purpose unknown.

#define O_RDLOCK   16

Read locked, not shared.

#define O_RDONLY   1
#define O_RDWR   (O_RDONLY | O_WRONLY)
#define O_SCAN   4096

The following are PlayStation BIOS extensions.

Set to scanning type. Real purpose unknown.

#define O_TRUNC   1024
#define O_WRLOCK   32

Write locked, not shared.

#define O_WRONLY   2
#define open (   filename,
  flags,
  ... 
)    open(filename, flags)

These are standard C library file I/O functions provided by the PSX BIOS.

Filenames have to be specified in this way: Where device specifies the device the file is on: "tty:" Console "cdrom:" CD-ROM "buXX:" Memory cards

When using cdrom: as device, append file version (;1) to filename Example: cdrom:README.TXT;1

Subdirectory paths have to be specified with backslashes (), like MS-DOS. Read and write operations can be carried only in blocks. Blocks are 2048 bytes for the CD-ROM device, and 128 bytes for memory cards.

Function Documentation

int close ( int  d)
int lseek ( int  fildes,
int  offset,
int  whence 
)
int open ( char *  filename,
int  flags 
)

In previous versions, the second argument for open() was named `mode'.

That was incorrect; now it is correctly named `flags'.

int read ( int  d,
void *  buf,
int  nbytes 
)
