OldRawFwrite

Syntax

int OldRawFwrite(FILE *rawfp,char *name,struct RadarParm *prm, struct RawData *raw,int32 recnum,int *rtab);

Header

superdarn/oldrawwrite.h

Library

oldraw

Description

The OldRawFwrite function writes a raw data record to an open stream.

The data is written to the open stream pointed to by the argument fp. The data record is contructed the radar parameter block pointed to by the argument prm and the raw data structure pointer to by the argument raw.

The associated record number is given by the argument recnum.

The raw data records are limited to a maximum of 75 ranges. However the data could consist of more ranges than this and some form of mapping from the actual number of ranges to the (75)allowed in the file is required. This is done by using the rtab argument which is a pointer to an array listing which actual range each of the (75) allowed in the file. If this argument is set to a NULL pointer then no mapping is done and the first (75) ranges are used.

Returns

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

Errors

On error, (-1) is returned.
