An information-handling system is disclosed that includes an improved application programmatic interface that allows application binary interfaces to be ported from one platform to another incompatible platform with minimal difficulty. Within the information-handling system, there are one or more processors; a storage system; one or more I/O controllers; a system bus connecting the processors, the storage system, and the I/O controller; and an operating system programmed for controlling the operation of the information-handling system. The application programmatic interface (API) operates in association with the operating program. The API provides a language and platform neutral interface for manipulating a particular variable list within the ABI and is portable from one platform to another.
