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; } Ali

Perfect! Thank you.
