Function CSTL_string_replace_n

pub unsafe extern "C" fn CSTL_string_replace_n(
    instance: CSTL_StringRef,
    first: *const c_char,
    last: *const c_char,
    ptr: *const c_char,
    count: usize,
    alloc: *mut CSTL_Alloc,
) -> bool

Replaces the characters in the range [first, last) with the first count characters of the string at ptr.

If the length of the resulting string is greater than CSTL_string_max_size() this function has no effect and returns false, otherwise it returns true.

If first == last, no operation is performed.

The range [first, last) must be valid and dereferenceable on instance.
