SmrFread

Syntax

int SmrFread(FILE *fp,struct RadarParm *prm, struct FitData,int beam);

Header

superdarn/smrread.h

Library

smr

Description

The SmrFread function reads a summary data record from an open stream.

The data is read from the open stream pointed to by the argument fp. The data is decoded and used to populate the radar parameter block pointed to by the argument prm and the fit data structure pointer to by the argument fit.

As summary files contain only a few beams from a scan, the function requires the first beam stored in the summary file so that it can detect the start of a scan. The first beam is given by the argument beam.

Returns

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

Errors

On error, (-1) is returned.
