NAME    [Toc]    [Back]

       EvmEventRead,  EvmEventWrite  -  Performs I/O of events to
       and from a file

SYNOPSIS    [Toc]    [Back]

       #include <evm/evm.h>

       EvmStatus_t EvmEventRead(
               EvmFd_t fd,
               EvmEvent_t *event ); EvmStatus_t EvmEventWrite(
               EvmFd_t fd,
               const EvmEvent_t event );

OPERANDS    [Toc]    [Back]

       For EvmEventRead(), the return  operand  created  for  the
       event  read. For EvmEventWrite(), the event to be written.
       The file descriptor to which the event should be  written,
       or from which it should be read.

DESCRIPTION    [Toc]    [Back]

       The  EvmEventRead()  routine creates a new event structure
       and populates it with an event read from the supplied file
       descriptor  (fd).  The  EvmEventDestroy()  routine must be
       used to destroy the new event when it is no longer needed.

       The  EvmEventWrite()  routine writes the supplied event to
       the specified file descriptor (fd).  It does  not  destroy
       the  event.  If  the event is no longer needed, the caller
       should call EvmEventDestroy().

RESTRICTIONS    [Toc]    [Back]

       condition was encountered while reading.  One of the arguments
