d_resize: Change the size of a file

This type of function is specified as part of the file system device driver interface and is called by fopen, ftruncate, and open to change the size of the special file. If the file is extended beyond its current size, the extended part will (logically) contain \0.

Note: This function type provides the interface definition for user-defined device drivers that are called by z/TPF system programs, and cannot be called from your application programs. See Special files for more information about user-defined device driver functions.
