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 type

       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

       2.8.0
