.sp
.BI "int gnutls_x509_crl_get_extension_data(gnutls_x509_crl_t " crl ", unsigned " indx ", void * " data ", size_t * " sizeof_data ");"
.SH ARGUMENTS

critical flag.  Use \fBgnutls_x509_crl_get_extension_info()\fP instead,
if you want to get data indexed by the extension OID rather than
sequence.
