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
