putenv Approach
The following describes the putenv approach. The putenv function call
permits the developer to directly place the ORACLE_SID and the
ORACLE_HOME environmental shell variables into a Pro*C program.
Perform the following:
1 Using an editor, open the Pro*C source file for editing.
2 Add the following line at the top of the source file:
#include <stdlib.h>
3 Near the beginning of main, add the following two lines of code:
putenv ( "ORACLE_SID=<ORACLE_SID_name>" );
putenv ( "ORACLE_HOME=<ORACLE_HOME_name>” );
where ORACLE_SID_name is the name of the database instance on the
server and ORACLE_HOME_name is the ORACLE_HOME directory on
the server.
