I have a routine that can accept multiple parameters.  I'm having a problem
getting the compiler to accept a prototype so that it doesn't complain
that I have "too many actual arguments".

The routine takes a string of characters with fields separated by |'s and
extracts the fields and places them into the arguments that it is called
with.

For example:

	buffer = "field1|field2|field3" 

		would be extracted with:

	pickit ( 3, buffer, fld1, fld2, fld3);

		and
			
	buffer = "field1|field2|field3|field4" 

		would be extracted with:

	pickit ( 4, buffer, fld1, fld2, fld3, fld4);
	
The routine works great.  But the compiler continues to complain
with warning errors that "too many actual parameters" are being called.

I have tried several variations, all with the same results.

Below is the routine, Any suggestions?

----- pickit routine ------

pickit(int nargs, char *buffer, char *args)
{
	char **p;
	int  i,	l;

	p = &args;
	l=0;

	/* First check that they are enough fields for the request */
	
	for ( i = strlen (buffer) ; i > 0 ; i-- )
		if ( buffer[ i - 1 ] == '|' )
			l++;

	if ( l < nargs )
		return(ERROR);

	/* Now extract the fields */
	
	for ( i = 0 ; i < nargs ; i++ )
		{
		while ( ( *( *p )++ = *buffer++ ) ! = '|' );
		*( *p - 1 ) = '\0';
		p++;
		}

	return(TRUE);
}

----- end of pickit routine ------

Below is the actual error message that I get from the compiler [only one
shown for brevity]

ts2umodify.c(122) : warning C4020: 'pickit' : too many actual parameters

The system I'm using is...

System: Intel 386DX Clone
OS:	SCO Xenix 386 2.3.[23]
Dev:	SCO Development System 2.3.1b

Thanks for the help
