VecForeachInRangeIdxDescription
Iterate over elements in a specific range of the given vector v at each index idx. The variables var and idx are declared and defined by this macro. idx will start from start and will go till end - 1
Parameters
| Name | Direction | Description |
|---|---|---|
v | in,out | Vector to iterate over. |
var | in | Name of variable to be used which’ll contain value at iterated index idx. |
idx | in | Name of variable to be used for iterating over indices. |
start | in | Starting index (inclusive). |
end | in | Ending index (exclusive). |
Success
The body is executed for each element of the vector v from the start index to the end-1 index.
Failure
If the vector v is NULL, its length is zero, or the range is invalid, the loop body will not be executed. Any access to an invalid index will result in a fatal log message and program termination.
