NAME
       gnutls_x509_crq_get_subject_alt_name - API function

SYNOPSIS
       #include <gnutls/x509.h>

       int gnutls_x509_crq_get_subject_alt_name(gnutls_x509_crq_t crq, unsigned
       int seq, void * ret, size_t * ret_size, unsigned int * ret_type, unsigned
       int * critical);

ARGUMENTS
       gnutls_x509_crq_t crq
                   should contain a gnutls_x509_crq_t type

       unsigned int seq
                   specifies the sequence number of the alt name, 0 for the
                   first one, 1 for the second etc.

       void * ret  is the place where the alternative name will be copied to

       size_t * ret_size
                   holds the size of ret.

       unsigned int * ret_type
                   holds the gnutls_x509_subject_alt_name_t name type

       unsigned int * critical
                   will be non-zero if the extension is marked as critical (may
                   be null)

DESCRIPTION
       This function will return the alternative names, contained in the given
       certificate.  It is the same as gnutls_x509_crq_get_subject_alt_name()
       except for the fact that it will return the type of the alternative name
       in  ret_type even if the function fails for some reason (i.e.  the buffer
       provided is not enough).

RETURNS
       the alternative subject name type on success, one of the enumerated
       gnutls_x509_subject_alt_name_t.  It will return
       GNUTLS_E_SHORT_MEMORY_BUFFER if  ret_size is not large enough to hold the
       value.  In that case  ret_size will be updated with the required size.
       If the certificate request does not have an Alternative name with the
       specified sequence number then GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE is
       returned.

SINCE
       2.8.0
