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_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
