Hi,
I need some advie on compilig a C file, some history to aid in this process, I have a daemon.pc file that I run through the Pro*C precompiler using the following command
Proc iname=daemon userid=abre/abre sqlcheck=semantics
The daemon.pc file renders to the daemon.c file without any probelms, however, when I try and compile the daemon.c file I am returned with enough errors to choke on;
"daemon.c", line 109: warning: no explicit type given
"daemon.c", line 111: warning: no explicit type given
"daemon.c", line 113: warning: no explicit type given
"daemon.c", line 114: warning: no explicit type given
"daemon.c", line 115: warning: no explicit type given
"daemon.c", line 273: warning: implicit function declaration: sqlglm
"daemon.c", line 277: warning: implicit function declaration: exit
"daemon.c", line 292: warning: old-style declaration or incorrect type for: main
"daemon.c", line 462: warning: implicit function declaration: system
---------------
Below is the original daemon.pc code;
----------------
#include <stdio.h>
#include <string.h>
EXEC SQL include sqlca;
EXEC SQL begin declare section;
char *uid = "abre/abre";
int status;
varchar command[[20]];
varchar value[[2000]];
varchar return_name[[30]];
EXEC SQL end declare section;
void connect_error()
{
char msg_buffer[[512]];
int msg_length;
int buffer_size = 512;
EXEC SQL whenever sqlerror continue;
sqlglm(msg_buffer, &buffer_size, &msg_length);
printf("Daemon error while connecting:n");
printf("%.*sn", msg_length, msg_buffer);
printf("Daemon quitting.n");
exit(1);
}
void sql_error()
{
char msg_buffer[[512]];
int msg_length;
int buffer_size = 512;
EXEC SQL whenever sqlerror continue;
sqlglm(msg_buffer, &buffer_size, &msg_length);
printf("Daemon error while executing:n");
printf("%.*sn", msg_length, msg_buffer);
printf("Daemon continuing.n"); } main()
{
EXEC SQL whenever sqlerror do connect_error();
EXEC SQL connect :uid;
printf("Daemon connected.n");
EXEC SQL whenever sqlerror do sql_error();
printf("Daemon waiting...n"); while (1)
{
EXEC SQL EXECUTE
begin
:status := dbms_pipe.receive_message('daemon');
if :status = 0 then
dbms_pipe.unpack_message(:command);
end if;
end;
END-EXEC;
if (status == 0)
{
command.arr[[command.len]] = ' ';
if (!strcmp((char *)command.arr, "STOP"))
{
printf("Daemon exiting.n");
break;
}
else if (!strcmp((char *)command.arr, "SYSTEM"))
{
EXEC SQL EXECUTE
begin
dbms_pipe.unpack_message(:return_name);
dbms_pipe.unpack_message(:value);
end;
END-EXEC;
value.arr[[value.len]] = ' ';
printf("Will execute system command '%s'n", value.arr);
status = system(value.arr);
EXEC SQL EXECUTE
begin
dbms_pipe.pack_message('done');
dbms_pipe.pack_message(:status);
:status := dbms_pipe.send_message(:return_name);
end;
END-EXEC;
if (status)
{ printf("Daemon error while responding to system command.");
printf(" status: %dn", status);
}
}
else if (!strcmp((char *)command.arr, "SQL"))
{
EXEC SQL EXECUTE
begin
dbms_pipe.unpack_message(:return_name);
dbms_pipe.unpack_message(:value);
end;
END-EXEC;
value.arr[[value.len]] = ' ';
printf("Will execute sql command '%s'n", value.arr);
EXEC SQL whenever sqlerror continue;
EXEC SQL EXECUTE IMMEDIATE :value;
status = sqlca.sqlcode;
EXEC SQL whenever sqlerror do sql_error();
EXEC SQL EXECUTE
begin
dbms_pipe.pack_message('done');
dbms_pipe.pack_message(:status);
:status := dbms_pipe.send_message(:return_name);
end;
END-EXEC;
if (status)
{
printf("Daemon error while responding to sql command.");
printf(" status: %dn", status);
}
}
else
{
printf("Daemon error: invalid command '%s' received.n", command.arr);
}
}
else {
printf("Daemon error while waiting for signal.");
printf(" status = %dn", status);
}
}
EXEC SQL commit work release; }
--------------------
Any help and advice would be most appreciated.
