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.
