int rd (  int  fd, char *  data, int *  len, int  maxlen )

Read a data segment from a network stream. This function will block until the specified length has been received. Parameters: fd  [in] file descriptor data  [out] buffer to store the read data len  [out] received length in bytes maxlen  [in] maximum length of data buffer in bytes Returns: received data length in bytes, or -1 on error.

int wt (  int  fd, char *  data, int  len )

Write a data segment to a network stream. Parameters: fd  [in] file descriptor data  [in] buffer that holds data to write len  [out] received length in bytes Returns: actually written data length in bytes, or -1 on error.
