Table of contents## Procedurewnincd_c ( Included in a double precision window ) SpiceBoolean wnincd_c ( SpiceDouble left, SpiceDouble right, SpiceCell * window ) ## AbstractDetermine whether an interval is included in a double precision window. ## Required_ReadingWINDOWS ## KeywordsWINDOWS ## Brief_I/OVARIABLE I/O DESCRIPTION -------- --- -------------------------------------------------- left, right I Input interval. window I Input window. The function returns SPICETRUE if the input interval is included in ---is a subset of some interval in---window. ## Detailed_Inputleft, right are the endpoints of an interval, which may or may not be contained in one of the intervals in `window'. window is a window containing zero or more intervals. `window' must be declared as a double precision SpiceCell. CSPICE provides the following macro, which declares and initializes the cell SPICEDOUBLE_CELL ( window, WINDOWSZ ); where WINDOWSZ is the maximum capacity of `window'. ## Detailed_OutputThe function returns SPICETRUE if the input interval is included in the input window --- that is, if a(i) < left < right < b(i) - - - for some interval [ a(i), b(i) ] in `window' --- and is SPICEFALSE otherwise. ## ParametersNone. ## Exceptions1) The cardinality of the input `window' must be even. Left endpoints of stored intervals must be strictly greater than preceding right endpoints. Right endpoints must be greater than or equal to corresponding left endpoints. Invalid window data are not diagnosed by this routine and may lead to unpredictable results. 2) The order of the input interval's endpoints, `left' and `right', is not checked, and that this does not affect the result. 3) If the `window' cell argument has a type other than SpiceDouble, the error SPICE(TYPEMISMATCH) is signaled. The function returns the value SPICEFALSE. ## FilesNone. ## ParticularsNone. ## ExamplesLet window contain the intervals [ 1, 3 ] [ 7, 11 ] [ 23, 27 ] Then the following expressions are SPICETRUE ## RestrictionsNone. ## Literature_ReferencesNone. ## Author_and_InstitutionN.J.
