StrForeachPtrInRange
StrForeachPtrInRange
Description
Iterate over characters in a specific range of the given Str str (as pointers). This is a convenience macro that iterates over a range using an internally managed index and provides a pointer to each character. The variable chrptr is declared and defined by the underlying VecForeachPtrInRange macro as a pointer to the character type.
