OldFitInxWrite

Syntax
int OldFitInxWrite(int inxfp,int drec,int dnum,struct RadarParm *prm);
Header
superdarn/oldfitwrite.h
Library
oldfit
Description

The OldFitInxWrite function writes a record to an index file of a fit data file.

The record is written to the file with the descriptor given by the argument inxfd.The argument drec, is the block number of the start of the fit record in the associated fit file and the argument dnum, is the number of blocks required to store the fit data.

The final argument prm is a pointer to the radar parameter block associated with the fit data.

Returns
Returns zero on success. On error, (-1) is returned.
Errors
On error, (-1) is returned.
