This header requires only a conforming C99 (or higher) compiler +and standard library. + +The usage is identical to your system's sprintf() and vsprintf(), respectively, +except that the first argument is a pointer to a pointer to char, rather than +a pointer directly to a char buffer. On a successful call, a new buffer large +enough to hold the resulting string is allocated and assigned through the +first parameter. This buffer must be passed to free() to avoid memory leaks.
