gnutls_x509_crq_get_extension_by_oid(3) gnutls gnutls_x509_crq_get_extension_by_oid(3) NAME
gnutls_x509_crq_get_extension_by_oid - API function SYNOPSIS
#include <gnutls/x509.h> int gnutls_x509_crq_get_extension_by_oid(gnutls_x509_crq_t crq, const char * oid, int indx, void * buf, size_t * buf_size, unsigned int * critical); ARGUMENTS
gnutls_x509_crq_t crq should contain a gnutls_x509_crq_t structure const char * oid holds an Object Identifier in a null terminated string int indx In case multiple same OIDs exist in the extensions, this specifies which to get. Use (0) to get the first one. void * buf a pointer to a structure to hold the name (may be null) size_t * buf_size initially holds the size of buf unsigned int * critical will be non-zero if the extension is marked as critical DESCRIPTION
This function will return the extension specified by the OID in the certificate. The extensions will be returned as binary data DER encoded, in the provided buffer. RETURNS
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error code in case of an error. If the certificate does not contain the specified extension GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned. SINCE

gnutls_x509_crq_get_attribute_info(3) gnutls gnutls_x509_crq_get_attribute_info(3) NAME
gnutls_x509_crq_get_attribute_info - API function SYNOPSIS
#include <gnutls/x509.h> int gnutls_x509_crq_get_attribute_info(gnutls_x509_crq_t crq, int indx, void * oid, size_t * sizeof_oid); ARGUMENTS
gnutls_x509_crq_t crq should contain a gnutls_x509_crq_t structure int indx Specifies which attribute number to get. Use (0) 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 . DESCRIPTION
This function will return the requested attribute OID in the certificate, and the critical flag for it. The attribute OID will be stored as a string in the provided buffer. Use gnutls_x509_crq_get_attribute_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. 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
