RadarYMDHMSGetSite

Syntax
struct RadarSite *RadarYMDHMSGetSite(struct Radar *ptr,int yr, int mo,int dy,int hr,int mt,int sc);
Header
superdarn/radar.h
Library
radar
Description

The RadarYMDHMSGetSite function locates the hardware information for one of the radars.

The argument ptr is a pointer to the structure containing the radar information block. The radar hardware parameters can vary over time, so the time for which the hardware information is requested is specified by the arguments yr, mo,dy,hr,mt,sc giving the year, month, day, hour, minute and second.

Returns
Returns a pointer to the radar hardware information for the desired time. On error, a NULL pointer is returned.
Errors
On error, a NULL pointer is returned.
Example
