pciterate

int  pciterate(int handle)

This function can be used to iterate over all the points which were found in a pcopen query. The first argument is the handle returned by pcopen. The function returns 1 while there are points left in the iteration loop, or 0 when there are no further points. This lets you use the function as the condition in a while loop.

Warnings:

• It is not possible to nest pcunshaded or pciterate loops for the same handle. That is, for a single pcopen call, only one pcunshaded or pciterate loop may be entered.
• Computations involving derivatives inside pcunshaded loops may have slightly different results. If derivatives are required for variables which aren’t set by pcimport it may be better to pre-compute the derivatives before the pcunshaded loop is entered.
