EvmEventRead(3)						       EvmEventRead(3)

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

SYNOPSIS
       #include <evm/evm.h>

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

OPERANDS
       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
       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
       None

RETURN VALUES
       The operation was completed without error.   En	end-of-file  condition
       was  encountered	 while	reading.  One of the arguments to the function
       was invalid.  An operation failed because an attempt  to	 acquire  heap
       memory  failed.	 An  error  occurred while reading an event.  An error
       occurred while writing an event.

ERRORS
       None

LIBRARY
       EVM Support Library (libevm.so, libevm.a)

FILES
