Hi,

I've got FreeTDS (only just tested with TSQL) working on our OpenVMS system 
(had some trouble with iconv, but solved that almost the same as I saw later 
in the mailinglist).

Our OpenVMS version is 7.3, C Compiler is version 6.4, SQL Server are 
2000-versions. TCP/IP stack on the VMS server is TCPWare 5.3.

The TCPWare implementation has the following definition for the 
sockaddr_in-struct:

/*
** Socket Address Structure (internet style):
*/
struct sockaddr_in {
     short       sin_family;
     unsigned short    sin_port;
     struct in_addr    sin_addr;
     char        sin_zero[8];
};


struct in_addr {
     unsigned long s_addr;
};

In login.c the following code is used:

        sin.sin_addr.s_addr = 
inet_addr(tds_dstr_cstr(&connect_info->ip_addr));
        if (sin.sin_addr.s_addr == -1) {
		tdsdump_log(TDS_DBG_ERROR, "%L inet_addr() failed, IP = %s\n", 
connect_info->ip_addr);
                tds_free_socket(tds);
                return TDS_FAIL;
        }

I get a compiler message on the compare. Seems logical, because an unsigned 
long is very unlikely to become negative.

Is this TCPWare specific ?


Further I got some more compiler messages due to signed/unsigned typedefs.

convert.c
=========
TDS_INT
tds_convert(TDSCONTEXT * tds_ctx, int srctype, const TDS_CHAR * src, 
TDS_UINT srclen, int desttype, CONV_RESULT * cr)
{
        TDS_INT length = 0;

        assert(srclen >= 0 && srclen <= 2147483647u);

The assert statement is checking for values that are already defined by the 
type TDS_UINT. Is TDS_UINT for some systems/compilers of another type ?

read.c/write.c
==============
tds_iconv function return value is of size_t (and checked for "-1" values). 
The size_t type is defined in the DEC C headers as an unsigned int.

user.c/meber.c
==============
tds->in_len is checked for "-1" values. It is defined as unsigned in tds.h.


Should I worry about these compiler messages (and make adjustments) or 
should I just ignore and enjoy a working FreeTDS library ?

I still have to find out how to link the library to a Fortran-program. 
Anyone has any experience (examples) for doing this on VMS ?

Regards,
Gert
