EvmEventRead(3) 					     Library Functions Manual						   EvmEventRead(3)

NAME

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

LIBRARY

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

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 parameter 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

FILES

       None
