Syntax

int RadarGetCodeNum(struct RadarNetwork *ptr,int stid);

Header

superdarn/radar.h

Library

radar

Description

The RadarGetCodeNum function locates how many identifier codes are defined for one of the radars.

The argument ptr is a pointer to a structure containing the information for the entire network. The radar identifier number for the radar is given by the argument stid.

Returns

Returns the number of identifier codes defined for a radar. On error, (-1) is returned.

Errors

On error, (-1) is returned.
