.SH NAME
gnutls_ocsp_req_get_extension \- API function
.SH SYNOPSIS
.B #include <gnutls/ocsp.h>
.sp
.BI "int gnutls_ocsp_req_get_extension(gnutls_ocsp_req_const_t " req ", unsigned " indx ", gnutls_datum_t * " oid ", unsigned int * " critical ", gnutls_datum_t * " data ");"
.SH ARGUMENTS
.IP "gnutls_ocsp_req_const_t req" 12
should contain a \fBgnutls_ocsp_req_t\fP type
.IP "unsigned indx" 12
Specifies which extension OID to get. Use (0) to get the first one.
.IP "gnutls_datum_t * oid" 12
will hold newly allocated buffer with OID of extension, may be NULL
.IP "unsigned int * critical" 12
output variable with critical flag, may be NULL.
.IP "gnutls_datum_t * data" 12
will hold newly allocated buffer with extension data, may be NULL
.SH "DESCRIPTION"
This function will return all information about the requested
extension in the OCSP request. The information returned is the
OID, the critical flag, and the data itself. The extension OID
will be stored as a string. Any of \fIoid\fP , \fIcritical\fP , and \fIdata\fP may
be NULL which means that the caller is not interested in getting
that information back.
The caller needs to deallocate memory by calling \fBgnutls_free()\fP on
\fIoid\fP \->data and \fIdata\fP \->data.
Since 3.7.0 \fIoid\fP \->size does not account for the terminating null byte.
.SH "RETURNS"
On success, \fBGNUTLS_E_SUCCESS\fP (0) is returned, otherwise a
negative error code is returned. If you have reached the last
extension available \fBGNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE\fP will
be returned.
.SH "REPORTING BUGS"
