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 structure
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_MEM- ORY_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 certifi- cate request does not have an Alternative name with the specified sequence number then GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE is returned.
