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
