Method Detail

Open

public static PRFDProxy Open(java.lang.String name,
                             int flags,
                             int mode)

Open the file at name (with the specified flags and mode) and create a new PRFDProxy (to a NSPR PRFileDesc *) for that file. See also: PR_Open in /usr/include/nspr4/prio.h

NewTCPSocket

public static PRFDProxy NewTCPSocket()

Open a new TCP Socket and create a new PRFDProxy for that socket. See also: PR_NewTCPSocket in /usr/include/nspr4/prio.h

NewBufferPRFD

public static PRFDProxy NewBufferPRFD(BufferProxy read_buf,
                                      BufferProxy write_buf,
                                      byte[] peer_info)

Create a new j_buffer backed PRFileDesc, mimicing a TCP socket with the specified peer_info. See also: newBufferPRFileDesc in org/mozilla/jss/ssl/javax/BufferPRFD.h

Close

public static int Close(PRFDProxy fd)

Close an existing PRFDProxy. See also: PR_Close in /usr/include/nspr4/prio.h

Shutdown

public static int Shutdown(PRFDProxy fd,
                           int how)

Shutdown an existing PRFDProxy. This is usually used with TCP modes. See also: PR_Shutdown in /usr/include/nspr4/prio.h

Read

public static byte[] Read(PRFDProxy fd,
                          int amount)

Read up to amount bytes from a PRFDProxy. See also: PR_Read in /usr/include/nspr4/prio.h

Recv

public static byte[] Recv(PRFDProxy fd,
                          int amount,
                          int flags,
                          long timeout)

Recv up to amount bytes from a PRFDProxy, given the specified receive flags and timeout value. See also: PR_Recv in /usr/include/nspr4/prio.h

Write

public static int Write(PRFDProxy fd,
                        byte[] buf)

Write the specified bytes to the PRFDProxy. Note: Unlike PR_Write, this method assumes the entire buffer is being written. See also: PR_Write in /usr/include/nspr4/prio.h

Send

public static int Send(PRFDProxy fd,
                       byte[] buf,
                       int flags,
                       long timeout)

Send the specified bytes via the PRFDProxy, given the specified send flags and timeout value. See also: PR_Send in /usr/include/nspr4/prio.h

GetError

public static int GetError()

Get the value of the current PR error. This is cleared on each NSPR call. See also: PR_GetError in /usr/include/nspr4/prio.h

GetErrorText

public static java.lang.String GetErrorText()

Get the error text of the current PR error. This is cleared on each NSPR call. See also: PR_GetErrorText in /usr/include/nspr4/prio.h

ErrorToName

public static java.lang.String ErrorToName(int code)

Get the constant name of the current PR error. This is cleared on each NSPR call. See also: PR_ErrorToName in /usr/include/nspr4/prio.h
