FitWrite

Syntax

int FitWrite(int fid,struct RadarParm *prm, struct FitData *fit);

Header

superdarn/fitcfit.h

Library

fit

Description

The FitWrite function writes a fitacf data record to an open file.

The data is written to the file with the descriptor given by the argument fid. If fid is set to (-1) then the function will just calculate the number of bytes required to store the data. The data record is contructed the radar parameter block pointed to by the argument prm and the fit data structure pointer to by the argument fit.

Returns

Returns the number of bytes written on success. On error, (-1) is returned.

Errors

On error, (-1) is returned.
