RexxUtil is a Dynamic Link Library (DLL) package for Windows and *nix platforms; the package contains external Rexx functions. These functions:
All of the RexxUtil functions are registered by the ooRexx interpreter on startup so there is no need to register the functions either individually or via the SysLoadFuncs function.
8.1. A Note on Error Codes
On Windows, some of the REXXUTIL functions return operating system error codes on failure. The SysGetErrorText (
Section 8.30, “SysGetErrortext”) function can be used retrieve a description of system error code. In addition, the meaning of these error return codes can be looked up in the Windows Operating System documentation provided by Microsoft.
The documentation is called the MSDN Library. The library is provided online for anyone to access. Plus, since May 2006, Microsoft has also provided the ISO images for the library free of charge. Anyone can download the ISOs, burn them to a CD, and install the library locally on their system.
