I have the following C struct from ldap.h

typedef struct ldapmod {
	int	mod_op;
	char *mod_type;
	union mod_vals_u {
		char **modv_strvals;
		struct berval **modv_bvals;
	} mod_vals;
#define mod_values	mod_vals.modv_strvals
#define mod_bvalues	mod_vals.modv_bvals
} LDAPMod;

It is used like this:
LDAPMod title;
title.mod_values = x;

I wonder how can I write the line 'title.mod_values = x;' in D.
Currently I do like this:
	
struct ldapmod {
	int	mod_op;
	char* mod_type;
	union mod_vals_u {
		char**  modv_strvals;
		berval** modv_bvals;
	}
	mod_vals_u mod_vals;
}
alias ldapmod LDAPMod;

LDAPMod title;
title.mod_vals.modv_strvals = x;

A pair of @property functions would work, one of which may be unnecessary:

alias int berval;

struct ldapmod {
    int    mod_op;
    char* mod_type;
    union mod_vals_u {
        char**  modv_strvals;
        berval** modv_bvals;
    }
    mod_vals_u mod_vals;

    char** mod_values() @property
    {
        return mod_vals.modv_strvals;
    }

    void mod_values(char** value) @property
    {
        mod_vals.modv_strvals = value;
    }

    // similarly for mod_bvalues...
}
alias ldapmod LDAPMod;

void main()
{
    LDAPMod title;
    char** x;
    // title.mod_vals.modv_strvals = x;
    title.mod_values = x;
}

Perfect! Thank you.
