NAME
cgGetArraySize - get the size of one dimension of an array parameterSYNOPSIS
#include <Cg/cg.h>
int cgGetArraySize( CGparameter param, int dimension );
PARAMETERS
- param
- The array parameter handle.
- dimension
- The array dimension whose size will be returned.
RETURN VALUES
Returns the size of param if param is an array.Returns 0 if param is not an array, or an error occurs.
DESCRIPTION
cgGetArraySize returns the size of the given dimension of the array specified by param. cgGetArraySize is used when inspecting an array parameter in a program.EXAMPLES
/* Compute the number of elements in an array, in the */ /* style of cgGetArrayTotalSize(param) */ if (cgIsArray(param)) { int dim = cgGetArrayDimension(param); int elements = cgGetArraySize(param, 0); for (int i = 1; i < dim; i++) { elements *= cgGetArraySize(param, i); } }
ERRORS
CG_INVALID_DIMENSION_ERROR is generated if dimension is less than 0.CG_INVALID_PARAM_HANDLE_ERROR is generated if param is not a valid parameter.
