OldRawHeaderWrite

Syntax

int OldRawHeaderWrite(int fid,char *name,char *version,int thr,char *text);

Header

superdarn/oldrawwrite.h

Library

oldraw

Description

The OldRawHeaderWrite function writes a raw header record to an file.

The header is written to the file with descriptor given by the argument fid. The name, version and descriptive text to store in the header are given by the zero terminated strings pointed to by the arguments name, version and text. The argument thr, defines the threshold applied to the lag-zero power. Ranges with lag zero power less than half the value of the noise multiplied by this threshold are ignored.

Returns

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

Errors

On error, (-1) is returned.
