StrForeachReverse
StrForeachReverse
Description
Iterate over each character chr of the given Str str in reverse order. This is a convenience macro that iterates backward using an internally managed index. The variable chr is declared and defined by the underlying VecForeachReverse macro.
Parameters
| Name | Direction | Description |
|---|---|---|
str |
in,out | Str to iterate over. |
chr |
in | Name of the variable to be used which will contain the character of the current element during iteration. The type of chr will likely be the character type used by the Str implementation (e.g., char). |
