Function Documentation

xerfft_()

int xerfft_	(	char *	srname,
		integer *	info,
		ftnlen
	)

Purpose

XERFFT is an error handler for library FFTPACK version 5.1 routines. It is called by an FFTPACK 5.1 routine if an input parameter has an invalid value. A message is printed and execution stops.

Installers may consider modifying the STOP statement in order to call system-specific exception-handling facilities.

Arguments

SRNAME (input) CHARACTER*6 The name of the routine which called XERFFT.

INFO (input) INTEGER When a single invalid parameter in the parameter list of the calling routine has been detected, INFO is the position of that parameter. In the case when an illegal combination of LOT, JUMP, N, and INC has been detected, the calling subprogram calls XERFFT with INFO = -1.
