Function Declaration and Defintion Problem

Amit_Basnak

Dear Friends

I am giving the following command to build the server executableon
HP-UX
/opt/aCC/bin/aCC -o SOAPServer SOAPServer.o WFWuListService.o
WFWuListImpl.o WFWuListStructs.o WFWuList.o
-I/opt/systinet/server_cpp65/include/ -I../.. +DD64
/opt/systinet/server_cpp65/lib/libwasp.sl
/opt/systinet/server_cpp65/lib/libwasp_stl.sl -ldcekt -lpthread

and Im getting the following error
ld: Unsatisfied symbol "WF_ListWuClnt" in file WFWuListService.o
1 errors.
Which means WFWuListService.cpp, especially the spelling and definition
of WF_ListWuClnt needs to be checked .

My header file WFWuMYList1.h has the prototype declaration of
WF_ListWuClnt function which is

long WF_ListWuClnt (
unsigned char *process_id,
unsigned char *process_step_id,
unsigned char *cluster_id,

A function body for WF_ListWuClnt perhaps, that has the same prototype
as the one in your header?
Or link in an external library that defines it.

Try programming in C++ instead. Otherwise ask your question in a C
newsgroup.
You have a declaration for long WF_ListWuClnt(...) but i don't see its
implementation.
Also,
a) pointers are evil, use references or const references instead
b) #include <string>, not <string.h>
c) #include <cstdlib>
d) #include <cstudio>

Well the code looks more like C with classes, but it certainly doesn't
pass
for pure C.

implementation.

Click to expand...

Pointers are not evil. However having to manage memory is evil. Use
smart-pointers,
use std::vector instead of arrays and std::string for string handling.

Use references instead of pointers when the pointer cannot be NULL or
change what
it points to. Use pointers when you need to initialise it later, eg
scoping:

Foo * ptrToAFoo;
if ( some_condition_or_other )
{
ptrToAFoo = x;
}
else
{
ptrToAFoo = y;
}

and it might not be possible to use ? : notation in the above if it's
complex.

void function( const Foo & fooparam, Diagnostics * diagnostic_info =
NULL );

The above uses a const reference parameter and a non-const pointer
parameter.
The const reference must refer to a valid object. The pointer may be
NULL if the
caller doesn't want the function to write diagnostic information.
b) #include <string>, not <string.h>
Click to expand...

The equivalent for <string.h> is <cstring> but it's true that most of
the time you won't
need the C string library functions. If you do then use said:
c) #include <cstdlib>
Click to expand...
Most of the time but I think there might be some POSIX functions in
<stdlib.h> that
are not in <cstdlib>. I certainly know there are some POSIX functions
that haven't
made it into the C++-equivalent header but I can't remember exactly
which ones.
d) #include <cstudio>
Click to expand...
No, there is no 'u'. It is <cstdio>. Most of the time you won't need
this header though,
as you will be using iostream and equivalent instead.

Thanks Earl and Peter for your expert advice.
To give you more back ground , I am building a Server binary
usingSystinet Server for C++ .
Thanks for the information. The WF_ListWuClnt() function had
originally been usedwith DCE
DCE ( Distributed Computing Environment) calls which uses Interface
Definition language ( idl) . In WFClnt_dceOnlyRpc.h file this original
WF_ListWuClnt () call has been defined as below

extern AppReturnStatus WF_ListWuClnt(
#ifdef IDL_PROTOTYPES
/* [in] */ idl_char *process_id,
/* [in] */ idl_char *process_step_id,
/* [in] */ idl_char *cluster_id,
/* [in] */ WF_STRUCT_SEARCH *search_params,
/* [in] */ idl_char incl_active_wu,
/* [in] */ idl_short_int nbr_requested,
/* [out] */ WF_LIST_WORKUNIT_P_FE *workunit_array,
#endif
);

The modifying function I am writing with Systinet Server for C++ does
not use DCE and hence I converted WF_ListWuClnt () to normal C/C++
function type as

long WF_ListWuClnt (
unsigned char *process_id,
unsigned char
*process_step_id,
unsigned char *cluster_id,
WF_STRUCT_SEARCH *search_params,
char
incl_active_wu,
int
nbr_requested,
WF_LIST_WORKUNIT_P_FE *workunit_array
);

and used as in my own header file WFWuMYList1.h which I included in
the WFWuListService.cpp . And its implementation is concerned , the
return of WF_ListWuClnt () oflong type has been stored in
tResult = WF_ListWuClnt(
wfm_binding_h,
(unsigned char*) (const char*) process_id_,
(unsigned char*) (const char*) process_step_id_,
(unsigned char*) (const char*) cluster_id_,
&wf_struct_search_d,
incl_active_wu_,
nbr_requested_,
&ptrlistWU);
which is also in tResult.

While compiling with aCC under HP-Unix , I didnt get any error , The
error comes only while building the server executable and that too in
WFWuListService.o object file and as correctly pointed out by Earl that
link in an external library that defines it could be missing .
Thank you again for your time and the efforts that you put in this
question.
Please let me know whether the implementation of WF_ListWuClnt( )
as shown above is correct or needs to be modified .
Thanks
Amit

When I compiled with all WF_ListWuClnt( ) commented , It goes fine and
no error has been repored.
