Detailed Description

Basically the memDrv.c file provided by VxWorks, but protected.

memDrvX.c is a bug fix to the VxWorks file memDrv.c. The VxWorks original resulted in a value being written to address zero when memDevDelete() called iodDevFind() (by virtue of passing a NULL as the second argument). This version provides a dummy location into which iosDevFind() can write this value (the value is never actually used, or passed back, by memDevDelete()).
