Handle dynamic string.
In this string are always valid (you don't have NULL pointer, only empty string)
allocate space for length char
s | dynamic string |
length | new length |
copy a string from another
s | dynamic string |
src | source buffer |
Set string to a given buffer of characters.
s | dynamic string |
src | source buffer |
length | length of source buffer |
set a string from another buffer.
The string will use the supplied buffer (it not copy the string), so it should be a pointer returned by malloc.
s | dynamic string |
src | source buffer |
