RSL_get_closest_sweep
Synopsis
#include "rsl.h"
Sweep *RSL_get_closest_sweep(Volume *v,float sweep_angle,float limit);
Description
Return the closest sweep within a volume. Closeness is determined by the minimum absolute difference of sweep_angle and the elevation angle of the ray. The difference must be less than limit. If no such ray can be found, return NULL.
Return value
Upon successful completion, a pointer to the Sweep structure is returned. Otherwise, a NULL pointer is returned.
