NAME
gnutls_x509_crt_get_extension_info - Get extension id and criticalitySYNOPSIS
#include <gnutls/x509.h>int gnutls_x509_crt_get_extension_info(gnutls_x509_crt_t cert, int indx, void * oid, size_t * sizeof_oid, int * critical);
ARGUMENTS
- gnutls_x509_crt_t cert
- should contain a gnutls_x509_crt_t structure
- int indx
- Specifies which extension OID to send. Use zero to get the first one.
- void * oid
- a pointer to a structure to hold the OID
- size_t * sizeof_oid
- initially holds the maximum size of oid, on return holds actual size of oid.
- int * critical
- output variable with critical flag, may be NULL.
DESCRIPTION
This function will return the requested extension OID in the certificate, and the critical flag for it. The extension OID will be stored as a string in the provided buffer. Use gnutls_x509_crt_get_extension_data() to extract the data.If the buffer provided is not long enough to hold the output, then *sizeof_oid is updated and GNUTLS_E_SHORT_MEMORY_BUFFER will be returned.
Return 0 on success. A negative value may be returned in case of parsing error. If you have reached the last extension available GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.
