Libraries

In addition to the ANSI standard C Compiler libraries that WDC supplies we also provide additional library functions that are generally useful. The table below shows which are available for each product type. Some of these library functions have been proven with WDC's starter kits and some have not yet been proven. Contact Us for more information.

WDC has created many of the library functions usually found only with C Compilers for the 65xx Assembler. In addition, WDC provides library functions that are generally useful for creating a broad range of systems and applications. The table below shows which are available for each product. Some of these library functions have been proven with WDC's starter kits and some have not yet been proven. Contact Us for more information.
