Method Detail

initConstInt

public int initConstInt(int index)

Specified by:

initConstInt in interface Library

open

public int open(String arg0,
                int arg1,
                int arg2)

Description copied from interface: LibC

open or create a file for reading or writing

Specified by:

open in interface LibC

Parameters:

arg0 - String

arg1 - std libc open flags

arg2 - 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.

stat

public int stat(String arg0,
                LibC.stat arg1)

Description copied from interface: LibC

Get information on the named "name".

Specified by:

stat in interface LibC

Parameters:

arg0 - String

arg1 - Stat structure that will be filled with the current values

Returns:

-1 is returned if an error occurs, otherwise zero is returned

fcntl

public int fcntl(int arg0,
                 int arg1,
                 int arg2)

Description copied from interface: LibC

provides for control over descriptors.

Specified by:

fcntl in interface LibC

Parameters:

arg0 - a descriptor to be operated on by cmd

arg1 - one of the cmd constants

Returns:

a value that depends on the cmd.

write

public int write(int arg0,
                 byte[] arg1,
                 int arg2)

Description copied from interface: LibC

write output

Specified by:

write in interface LibC

Parameters:

arg0 - file descriptor

arg1 - data buffer to write

arg2 - 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.

close

public int close(int arg0)

Description copied from interface: LibC

delete a descriptor

Specified by:

close in interface LibC

Parameters:

arg0 - 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.

read

public int read(int arg0,
                byte[] arg1,
                int arg2)

Description copied from interface: LibC

read input

Specified by:

read in interface LibC

Parameters:

arg0 - file descriptor

arg1 - data buffer to read into

arg2 - 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

fstat

public int fstat(int arg0,
                 LibC.stat arg1)

Description copied from interface: LibC

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

Specified by:

fstat in interface LibC

Parameters:

arg0 - file descriptor

arg1 - Stat structure that will be filled with the current values

Returns:

-1 is returned if an error occurs, otherwise zero is returned

fsync

public int fsync(int arg0)

Description copied from interface: LibC

Flush output on a descriptor

Specified by:

fsync in interface LibC

Parameters:

arg0 - 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

public int lseek(int arg0,
                 long arg1,
                 int arg2)

Description copied from interface: LibC

reposition read/write file offset

Specified by:

lseek in interface LibC

Parameters:

arg0 - file descriptor

arg1 - the offset to seek to

arg2 - 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.

unlink

public int unlink(String arg0)

Description copied from interface: LibC

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

Specified by:

unlink in interface LibC

Parameters:

arg0 - String

Returns:

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