Expand description
Init a print buffer.
@param buf buffer to init @param size_init initial size (including the final 0) @param size_max maximum size; 0 means do not write anything, just count the length; 1 is replaced by the maximum value for automatic storage; any large value means that the internal buffer will be reallocated as needed up to that limit; -1 is converted to UINT_MAX, the largest limit possible.
