Protected mode C binding for PCMCIA card services interface

A method for implementing PCMCIA Card Services for at least one application program running on a computer system executing a Windows operating system, said method comprising the steps of:

• loading a Card Services driver into said computer system, said Card Services driver being software interrupt based;
• providing a translation Card Services dynamic link library, said translation Card Services dynamic link library comprising a library of translation C functions corresponding to a library of defined Card Services functions;
• calling a translation C function in said translation Card Services dynamic link library from said application program to perform a corresponding Card Services function, said application program passing at least one function parameter to said translation C function;
• placing said function parameter passed to said translation C function into a register for a Card Services software interrupt call into said Card Services driver;
• and
• calling said Card Services driver from said translation C function in said translation Card Services dynamic link library using a software interrupt call, said Card Services driver performing said Card Services functionality.
