void Show_Window_Frame | ( | char * | flag | ) |
Returns the window frame visibility setting.
flag | - A special constant: either "on" or "off". 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_Window_Frame() 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 PShow_Net_Window_Frame | ( | int | key_count, | |
const HC_KEY * | path_keys, | |||
char * | flag | |||
) |
Similar to Show_Window_Frame(), but returns the net effective setting along a discrete segment path.
key_count | - The size of pathkeys | |
path_keys | - An array of HC_KEY's delineating a path of segments. | |
flag | - A special constant: either "on" or "off". Passed by reference. Returned to user. |
By default, HOOPS will determine the Net attribute from the last specified key all the way to the root. If you add -1 at the end of the array, the PShow_Net routines will not proceed beyond the end of the last specified key.
