Developing applications

To develop applications, you must install the development version of the SNIA HBA API provided by the libhbaapi-devel RPM, link your application against the library, and load the library.

Procedure

  1. Install the development RPM for the SNIA HBA API.
    Use, for example, yum:
    # yum install libhbaapi-devel

    The development RPM libhbaapi-devel provides the necessary header files and .so symbolic links needed to program against the SNIA HBA API.

  2. Add the command line option -lHBAAPI during the linker step of the build process to link your application against the SNIA HBA API library.
  3. In the application, issue the HBA_LoadLibrary() call as the first call to load the library.
    The vendor-specific library libzfcphbaapi, in turn, supplies the function HBA_RegisterLibrary that returns all function pointers to the common library and thus makes them available to the application.
