const char *
sysdecode_ioctlname(unsigned long request);

The sysdecode_ioctlname() function returns the name of a device control request identified by request. A table of names is generated during the build of the sysdecode library from system headers that maps device control request values to the name of the corresponding C macro.

The sysdecode_ioctlname() function returns the name of a device control request if request is a known value; otherwise NULL.
