StrForeachPtrReverseDescription
Iterate over each character pointer chrptr of the given Str str in reverse order. This is a convenience macro that iterates backward using an internally managed index and provides a pointer to each character. The variable chrptr is declared and defined by the underlying VecForeachPtrReverse macro as a pointer to the character type.
Parameters
| Name | Direction | Description |
|---|---|---|
str | in,out | Str to iterate over. |
chrptr | in | Name of the pointer variable to be used which will point to the current character during iteration. The type of chrptr will likely be a pointer to the character type used by the Str implementation (e.g., char*). |
Usage example (Cross-references)
// Test StrForeachPtrReverse macro
bool test_str_foreach_ptr_reverse(void) {
printf("Testing StrForeachPtrReverse\n");
Str s = StrInitFromZstr("Hello");
size char_count = 0;
StrForeachPtrReverse(&s, chrptr, {
// Append the character (via pointer) to the result string
StrPushBack(&result, *chrptr);
