m_read

This call reads up to len bytes of data from the I/O stream fp into buffer.


Syntax:      int far m_read(FCB far *fp, char far *buffer, int len, int far *lenp) 
Parameters:  FCB far *fp - Pointer to the data to be read 
             char far *buffer - Pointer to the buffer to receive the data
             int len - Length of data (in bytes) to be read
             int far *lenp - This parameter identifies how many bytes were actually 
                             read. If *lenp != len and no error value
                             is returned, the end-of-file has been reached.  
Returns:     0 - if successful
