ZstrDupN

Description

Duplicates a string up to the specified length. Allocates a new buffer through alloc and copies at most n characters.

alloc is optional inside a Scope block (defaults to MisraScope).

Success

Returns a pointer to the newly allocated duplicate string.

Failure

Returns NULL if memory allocation fails.

Usage example (Cross-references)

        // the caller owns and may mutate the returned buffer. ZstrDupN's Zstr
        // return is just the project-wide convention for fresh allocations.
        result = (char *)ZstrDupN(StrBegin(&temp), StrLen(&temp), allocator_ptr);
        if (!result) {
            LOG_ERROR("Failed to allocate memory for string");
