gnutls_x509_crq_get_dn_by_oid - API function
int gnutls_x509_crq_get_dn_by_oid(gnutls_x509_crq_t crq, const char * oid, int indx, unsigned int raw_flag, void * buf, size_t * buf_size);
should contain a gnutls_x509_crq_t type
const char * oid
holds an Object Identifier in a null terminated string
In case multiple same OIDs exist in the RDN, this specifies
which to get. Use (0) to get the first one.
unsigned int raw_flag
If non-zero returns the raw DER data of the DN part.
void * buf
a pointer to a structure to hold the name (may be NULL)
size_t * buf_size
initially holds the size of buf
This function will extract the part of the name of the Certificate
request subject, specified by the given OID. The output will be
encoded as described in RFC2253. The output string will be ASCII
or UTF-8 encoded, depending on the certificate data.
Some helper macros with popular OIDs can be found in gnutls/x509.h
If raw flag is (0), this function will only return known OIDs as
text. Other OIDs will be DER encoded, as described in RFC2253 --
in hex format with a # prefix. You can check about known OIDs
GNUTLS_E_SHORT_MEMORY_BUFFER if the provided buffer is
not long enough, and in that case the * buf_size will be
updated with the required size. On success 0 is returned.
