31 * The following symbols are defined (or undefined) according to the RTL
32 * support VMS provides for the corresponding functions. These don't
33 * appear in config.h, so they're dealt with here.
38 /* The VMS C RTL has vfork() but not fork(). Both actually work in a way
39 * that's somewhere between Unix vfork() and VMS lib$spawn(), so it's
40 * probably not a good idea to use them much. That said, we'll try to
41 * use vfork() in either case.
46 * fwrite1() should be a routine with the same calling sequence as fwrite(),
47 * but which outputs all of the bytes requested as a single stream (unlike
48 * fwrite() itself, which on some systems outputs several distinct records
49 * if the number_of_items parameter is >1).
