Programming INMODs for UNIX-based Clients
Programming INMODs for UNIX-based Clients
In addition to the techniques for preparing INMODs listed in “Preparing the INMOD
Program” on page 216 which apply to all platforms, there are several rules that must be
followed only for developing C INMODs for UNIX-based clients. These are:
• The INMOD subroutine must be named _dynamn.
• The INMOD must be compiled with the MetaWare High C compiler.
• The compiled INMOD module must be linked into a shared object module.
Compiling and Linking a C INMOD on a UNIX-based Client
Note: For a description of the syntax diagrams used in this book, see Appendix A: “How to
Read Syntax Diagrams.”
The following syntax example can be used to compile a C INMOD on a UNIX-based client.
