.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The X509 \s-1ASN1\s0 allocation routines, allocate and free an
X509 structure, which represents an X509 certificate.
.PP
\&\fIX509_new()\fR allocates and initializes a X509 structure.
.PP
\&\fIX509_free()\fR frees up the \fBX509\fR structure \fBa\fR.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
If the allocation fails, \fIX509_new()\fR returns \fB\s-1NULL\s0\fR and sets an error
code that can be obtained by \fIERR_get_error\fR\|(3).
Otherwise it returns a pointer to the newly allocated structure.
.PP
\&\fIX509_free()\fR returns no value.

\&\fIX509_new()\fR and \fIX509_free()\fR are available in all versions of SSLeay and OpenSSL.
