Initialization and Clean Up Functions



QisBool_Create

Syntax:

void* QisBool_Create( char oError[1024]);

Function:

Initializes the library, acquires a license and returns a handle.

Outputs

char oError[1024]
- string buffer to contain any error message returned by the function call.



Returns

    non-null (handle to a single instance of QisBool) This handle will be used when calling the other functions
    null - failed

Note:

Must be called before any other function, except for a reserve license call, is made.




QisBool_Destroy

Syntax:

void QisBool_Destroy( void *bdll_handle );

Function:

Does cleanup associated with the library handle and returns the handle to the handle pool. It also releases all licenses taken by this handle.

Input:

bdll_handle
- handle to close

Return Codes:





QisBool_ReleaseArray

Syntax:

void QisBool_ReleaseArray(int* Polygon);

Function:

frees memory associated with the polygon that was created by a prior call to library function.

Inputs:

Polygon - the array of XY pairs.

Note:

Use this function following: QisBool_GetSliceEdges




QisBool_Release

Syntax:

void   QisBool_Release
             ( int*** ioXY, 
               int** ioNV, 
               int* ioN
             );

Function:

frees memory associated with the array of polygons and vertices that were created by a prior call to library function.

Inputs:

int*** ioXY
- pointer to the array of arrays of polygon vertices returned by a prior call to the library.

int** ioNV
- pointer to array of polygon vertex counts returned by a prior call to the library

int* ioN
- pointer to array containing the number of polygon arrays.

Note:

Use this function following calls to:

QisBool_Booleanize
QisBool_UnionMT
QisBool_BinaryMT
QisBool_PolyConvexing
QisBool_PathToBoundaries
