since this is from a c library you should define {$packrecords c} on
the unit with this code.type BIGNUM = bignum_st; PBIGNUM = ^bignum_st; bignum_st = record d: PBN_ULONG; top: cint; dmax: cint; neg: cint; flags: cint; end; TBN_bn2hex = function (const a: PBIGNUM): PChar; cdecl; As you can see this code won't compile, you need to also find the declaration of BN_ULONG and define it. Also put ctypes on the uses clause. -- Felipe Monteiro de Carvalho _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
