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