cxErrorCode cxPickHitPointGet( cxPick *pick, int n, long *index)
integer function cxPickHitPointGet(pick,n,index) integer pick integer n integer index
- Pick data structure to interrogate.
- Index of hit in pick structure.
- Returned index of the point in a point set.
The function returns cx_err_none on success. A non-zero value is returned in case of an error. This will usually be because the hit is not of the proper object type.
The user can tell the function not to get information on a particular field by passing a NULL pointer value. You need not create dummy variables in the calling routine which calls cxPickHitPointGet, because the request is simply ignored when the pointer comes in NULL.
