Method Detail

write

public static final int write(int fildes,
                              byte[] buf)
                       throws NativeErrorException

POSIX: pwrite, write - write on a file.

Parameters:

fildes - a valid file descriptor open for writing

buf - The byte array from which all bytes are to be retrieved for writing.

Returns:

The number of bytes written, possibly zero.

Throws:

NativeErrorException - if the return value of the native function indicates an error.

read

public static final int read(int fildes,
                             byte[] buf)
                      throws NativeErrorException

POSIX: pread, read - read from a file.

Parameters:

fildes - a valid file descriptor open for reading

buf - the byte array into which all bytes are to be transferred.

Returns:

The number of bytes read, possibly zero.

Throws:

NativeErrorException - if the return value of the native function indicates an error.

read

public static final int read(int fildes,
                             byte[] buf,
                             int off,
                             int nbyte)
                      throws NativeErrorException

POSIX: pread, read - read from a file.

Parameters:

fildes - a valid file descriptor open for reading

buf - the byte array into which bytes are to be transferred.

off - the start offset in buf to which the data is transferred.

nbyte - the maximum number of bytes to read.

Returns:

The number of bytes read, possibly zero.

Throws:

NullPointerException - if buf is null.

ArrayIndexOutOfBoundsException - if off or nByte out of bounds.

NativeErrorException - if the return value of the native function indicates an error.

write

public static final int write(int fildes,
                              byte[] buf,
                              int off,
                              int nbyte)
                       throws NativeErrorException

POSIX: pwrite, write - write on a file.

Parameters:

fildes - a valid file descriptor open for writing

buf - The byte array from which the bytes are to be retrieved for writing.

off - the start offset in buf.

nbyte - the number of bytes to write.

Returns:

The number of bytes written, possibly zero.

Throws:

NullPointerException - if buf is null.

ArrayIndexOutOfBoundsException - if off or nByte out of bounds.

NativeErrorException - if the return value of the native function indicates an error.
