NAME
gnutls_x509_crq_get_extension_data - API functionSYNOPSIS
#include <gnutls/x509.h>int gnutls_x509_crq_get_extension_data(gnutls_x509_crq_t crq, int indx, void * data, size_t * sizeof_data);
ARGUMENTS
- gnutls_x509_crq_t crq
- should contain a gnutls_x509_crq_t structure
- int indx
- Specifies which extension number to get. 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 oid
DESCRIPTION
This function will return the requested extension data in the certificate. The extension data will be stored as a string in the provided buffer.Use gnutls_x509_crq_get_extension_info() to extract the OID and critical flag. Use gnutls_x509_crq_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 in case of an error. If your have reached the last extension available GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.SINCE
