void | Show_Parameter_Size (int *size) |
void Show_Parameter | ( | int * | size, | |
float * | list | |||
) |
Returns the parameters that have been set on the currently open vertex.
size | The number of parameters set on the currently open vertex (the size of the parameters array). Passed by reference. Returned to user. | |
list | A one dimensional array of floating point vertex parameters. Passed by reference. Returned to user. |
When the value being passed back is a string, be sure you've declared your string variable to be long enough.
In C, "passed by reference" means that you have to allocate an appropriate variable, either statically or off the stack, and pass a pointer to that variable to the HOOPS routine. To generate a pointer to a variable C, you prefix the variable with a "&". In other languages you normally don't have to do anything different from usual.
The Show_Parameter routines will complain if they're called and the attribute is not actually set in the segment. Use Show_Existence() to avoid this, if necessary.
void Show_Parameter_Size | ( | int * | size | ) |
Returns the size of the list array. Always three (3) for now.
size | The number of parameters set on the currently open vertex (the size of the parameters array). Passed by reference. Returned to user. |
