Method Detail

fcntl

int fcntl(int fd,
          int cmd,
          int arg)

provides for control over descriptors.

Parameters:: fd - a descriptor to be operated on by cmd; cmd - one of the cmd constants; arg -
Returns:: a value that depends on the cmd.

open

int open(String name,
         int oflag,
         int mode)

open or create a file for reading or writing

Parameters:: name - String; oflag - std libc open flags; mode - the mode for any created file
Returns:: If successful, returns a non-negative integer, termed a file descriptor. Returns -1 on failure, and sets errno to indicate the error.

close

int close(int fd)

delete a descriptor

Parameters:: fd - a descriptor to be operated on by cmd
Returns:: Upon successful completion, a value of 0 is returned. Otherwise, a value of -1 is returned and the global integer variable errno is set to indicate the error.

fsync

int fsync(int fd)

Flush output on a descriptor

Parameters:: fd - a descriptor to be flushed
Returns:: Upon successful completion, a value of 0 is returned. Otherwise, a value of -1 is returned and the global integer variable errno is set to indicate the error.

lseek

int lseek(int fd,
          long offset,
          int whence)

reposition read/write file offset

Parameters:: fd - file descriptor; offset - the offset to seek to; whence - the kind of offset (SEEK_SET, SEEK_CUR, or SEEK_END)
Returns:: the resulting offset location as measured in bytes from the beginning of the file. If error, -1 is returned and errno is set to indicate the error.

read

int read(int fd,
         byte[] buf,
         int nbyte)

read input

Parameters:: fd - file descriptor; buf - data buffer to read into; nbyte - number of bytes to read
Returns:: the number of bytes actually read is returned. Upon reading end-of-file, zero is returned. If error, a -1 is returned and the global variable errno is set to indicate the error

write

int write(int fd,
          byte[] buf,
          int nbyte)

write output

Parameters:: fd - file descriptor; buf - data buffer to write; nbyte - number of bytes to read
Returns:: the number of bytes which were written is returned. If error, -1 is returned and the global variable errno is set to indicate the error.

fstat

int fstat(int fd,
          LibC.stat stat)

Get information on the open file with file descriptor "fd".

Parameters:: fd - file descriptor; stat - Stat structure that will be filled with the current values
Returns:: -1 is returned if an error occurs, otherwise zero is returned

stat

int stat(String name,
         LibC.stat stat)

Get information on the named "name".

Parameters:: name - String; stat - Stat structure that will be filled with the current values
Returns:: -1 is returned if an error occurs, otherwise zero is returned

unlink

int unlink(String name)

Remove the directory entry for name (may delete the file)

Parameters:: name - String
Returns:: If successful, returns a non-negative integer, termed a file descriptor. Returns -1 on failure, and sets errno to indicate the error.
