a question on open() and lseek()

[moi%brandeis.csnet at csnet-relay.arpa]

	The manual page for "open()" mentions that one of the flags one
	can specify with the call is O_APPEND.  It's supposed to request
	that all "write()"s be appended to the end of the file.  Is
	there any reason to use the sequence:
		f = open( file, O_WRONLY );
		lseek( f, 0, L_XTND );
	instead of the single call:
		f = open( file, O_WRONLY | O_APPEND );
	
	I saw the sequence used in a section of code where the single
	call would make sense.
