All common format specifiers are supported.</p> <p>BIO_vprintf() is similar to the vprintf() function found on many platforms, the output is sent to the specified BIO, <b>bio</b>, rather than standard output. All common format specifiers are supported. The argument list <b>args</b> is a stdarg argument list.</p> <p>BIO_snprintf() is for platforms that do not have the common snprintf() function. It is like sprintf() except that the size parameter, <b>n</b>, specifies the size of the output buffer.</p> <p>BIO_vsnprintf() is to BIO_snprintf() as BIO_vprintf() is to BIO_printf().</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>All functions return the number of bytes written, or -1 on error. For BIO_snprintf() and BIO_vsnprintf() this includes when the output buffer is too small.</p> <h1 id="COPYRIGHT">COPYRIGHT</h1> <p>Copyright 2017 The OpenSSL Project Authors.
