Chapter 5: Using INMOD and Notify Exit Routines
Programming INMODs for UNIX-based Clients
where
Syntax Element
gcc
Description
Call to the program that invokes the native C compiler
-m31 Generates code for a 32-bit environment.
-shared
-fPIC
shared-objectname
Flag that produces a shared object that can then be linked with other objects to
form an executable
Compiler option that generates Position Independent Code for all user exit
routines
Name of the shared object file. The shared-object-name can be any valid file
name. This is the name specified as:
• The INMOD modulename parameter of the IMPORT of the MultiLoad job
script.
• The EXIT name parameter for the NOTIFY option of the BEGIN MLOAD
and BEGIN DELETE MLOAD of the MultiLoad job script.
-o Output file name
Compiling and Linking a C INMOD on on IBM OS z/OS
Use the following syntax from the USS environment to compile and link source files to a DLL:
Note: Be sure to compile the INMOD and notify exit routines in 32-bit mode so that they are
compatible with Teradata TPump.
cc
-o
"MVS.PDSE.LOAD(module_name)"
"//MVS.PDSE.C(source_name.c)" -W c,dll,expo = -W l,dll

where
Syntax Element
Description
-o Name of the executable load module that is produced during the link-edit phase.
In the following example, a load module INMOD is placed in a z/OS PDSE
named PDSE.LOAD, and the source code, INMOD, is compiled as a member of
a z/OS PDSE named TEST.C:
cc -o "//PDSE.LOAD(INMOD)" "//TEST.C(INMOD)" -W
c,dll,expo -W l,dll
Member names are limited to eight characters.
-W c,dll,expo Options passed to the compiler phase to indicate that the source is to be
compiled as a dll with all functions exported.
-W l,dll Options passed to the link-edit phase to indicate that the module is linked as a dll.
