NAME¶
gnutls_x509_crt_get_extension_data - API function
SYNOPSIS¶
#include <gnutls/x509.h>
int gnutls_x509_crt_get_extension_data(gnutls_x509_crt_t cert,
int indx, void * data, size_t *
sizeof_data);
ARGUMENTS¶
- gnutls_x509_crt_t cert
- should contain a gnutls_x509_crt_t structure
- int indx
- Specifies which extension OID to send. Use (0) to get the first one.
- void * data
- a pointer to a structure to hold the data (may be null)
- size_t * sizeof_data
- initially holds the size of data
DESCRIPTION¶
This function will return the requested extension data in the certificate. The
extension data will be stored in the provided buffer.
Use
gnutls_x509_crt_get_extension_info() to extract the OID and critical
flag. Use
gnutls_x509_crt_get_extension_by_oid() instead, if you want
to get data indexed by the extension OID rather than sequence.
RETURNS¶
On success,
GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error
code is returned. If you have reached the last extension available
GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.
