.SH DESCRIPTION
.IX Header "DESCRIPTION"
\&\fBX509_REQ_get_extensions()\fR returns the first list of X.509 extensions
found in the attributes of \fIreq\fR.
The returned list is empty if there are no such extensions in \fIreq\fR.
The caller is responsible for freeing the list obtained.
.PP
\&\fBX509_REQ_add_extensions()\fR adds to \fIreq\fR a list of X.509 extensions \fIexts\fR,
which must not be NULL, using the default \fBNID_ext_req\fR.
This function must not be called more than once on the same \fIreq\fR.
.PP
\&\fBX509_REQ_add_extensions_nid()\fR is like \fBX509_REQ_add_extensions()\fR
except that \fInid\fR is used to identify the extensions attribute.
This function must not be called more than once with the same \fIreq\fR and \fInid\fR.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
\&\fBX509_REQ_get_extensions()\fR returns a pointer to \fBSTACK_OF(X509_EXTENSION)\fR
or NULL on error.
.PP
\&\fBX509_REQ_add_extensions()\fR and \fBX509_REQ_add_extensions_nid()\fR
return 1 on success, 0 on error.
