Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

     The memset and _fmemset functions set the first <count> bytes of
     <dest> to the character <c>.
 
     The _fmemset function is a model-independent (large model) form of
     the memset function and can be called from any point in the
     program.
 
     There is a semantic difference between the function version of
     memset and its intrinsic version. The function version supports
     huge pointers in compact-, large-, and huge-model programs, but
     the intrinsic version does not.
 
     Return Value
 
     The memset and _fmemset functions return a pointer to <dest>.
