/* The <sys/ptrace.h> header was introduced with 4.4BSD, and provided
the PT_* symbolic constants for the ptrace(2) request numbers. The
ptrace(2) prototype was added later to the same header on BSD.
SunOS and GNU/Linux have slightly different symbolic names for the
constants that start with PTRACE_*. System V still doesn't have
(and probably never will have) a <sys/ptrace.h> with symbolic
constants; the ptrace(2) prototype can be found in <unistd.h>.
Fortunately all systems use the same numerical constants for the
common ptrace requests. */
