VecForeachPtrInRangeDescription
Iterate over elements in a specific range of the given vector v (as pointers). This is a convenience macro that iterates over a range using an internally managed index and provides a pointer to each element. The variable var is declared and defined by this macro as a pointer to the vector’s data type.
Parameters
| Name | Direction | Description |
|---|---|---|
v | in,out | Vector to iterate over. |
var | in | Name of pointer variable to be used which’ll point to the current element. |
start | in | Starting index (inclusive). |
end | in | Ending index (exclusive). |
