How to Create a CDSA Add-In Module for

HP-UX

This section summarizes the steps involved in creating a CDSA add-in module.

By convention, the CDSA add-in module is named libxxx.1 for the first version of the library, where xxx is the library’s chosen name. If /usr/lib file system supports only short file names, limit the library name to 14 characters. The add-in libraries must reside in /usr/lib/cdsa.

1.Create a global unique identifier (GUID) for the add-in module on the system. On HP-UX, you can use /usr/bin/uuidgen to generate a GUID.

Example:

Issue the following from the command line: #/usr/bin/uuidgen -s

Output will resemble the following:

= { /* 714ed4ea-15d8-11d2-9be7-0060b0b6e655 */

0x714ed4ea, 0x15d8, 0x11d2, 0x9b, 0xe7,

{ 0x00, 0x60, 0xb0, 0xb6, 0xe6, 0x55 }

}

The “714ed4ea-15d8-11d2-9be7-0060b0b6e655” might be the literal name of the GUID, but in your source file, you can define it as follows:

CSSM_GUID my_addin_guid =

{ /* 714ed4ea-15d8-11d2-9be7-0060b0b6e655 */

0x714ed4ea, 0x15d8, 0x11d2, {0x9b, 0xe7, 0x00, 0x60, 0xb0, 0xb6, 0xe6, 0x55}

};

Then my_addin_guid can be used whenever a GUID is needed; for example:

•when you register the module to CSSM, pass &my_addin_guid to CSSM_RegisterServices().

•when you install the module, pass &my_addin_guid to CSSM_ModuleInstall().

•when you attach the module, pass &my_addin_guid to CSSM_ModuleAttach().
