<h1><a name="description">DESCRIPTION</a></h1>
|
|
<p>The X509 ASN1 allocation routines, allocate and free an
|
|
X509 structure, which represents an X509 certificate.</p>
|
|
<p>X509_new() allocates and initializes a X509 structure with reference count
|
|
<strong>1</strong>.</p>
|
|
<p>X509_free() decrements the reference count of <strong>X509</strong> structure <strong>a</strong> and
|
|
frees it up if the reference count is zero. If <strong>a</strong> is NULL nothing is done.</p>
|
|
<p>X509_up_ref() increments the reference count of <strong>a</strong>.</p>
|
|
<p>X509_chain_up_ref() increases the reference count of all certificates in
|
|
chain <strong>x</strong> and returns a copy of the stack.</p>
|
|
<p>
|
|

<h1><a name="notes">NOTES</a></h1>
|
|
<p>The function X509_up_ref() if useful if a certificate structure is being
|
|
used by several different operations each of which will free it up after
|
|
use: this avoids the need to duplicate the entire certificate structure.</p>
|
|
<p>The function X509_chain_up_ref() doesn't just up the reference count of
|
|
each certificate it also returns a copy of the stack, using sk_X509_dup(),
|
|
but it serves a similar purpose: the returned chain persists after the
|
|
original has been freed.</p>

|
|
<h1><a name="return_values">RETURN VALUES</a></h1>
|
|
<p>If the allocation fails, X509_new() returns <strong>NULL</strong> and sets an error
|
|
code that can be obtained by <em>ERR_get_error(3)</em>.
|
|
Otherwise it returns a pointer to the newly allocated structure.</p>
|
|
<p>X509_up_ref() returns 1 for success and 0 for failure.</p>
|
|
<p>X509_chain_up_ref() returns a copy of the stack or <strong>NULL</strong> if an error
|
|
occurred.</p>
