Although it is defined in AIX's system header `sys/ptrace.h` , its not been mentioned in AIX public documentation. For other defines, here is the link though: https://www.ibm.com/docs/en/aix/7.2?topic=p-ptrace-ptracex-ptrace64-subroutine > ersions.

We are actually using these defines do some emulation in the NativeProcess files, hence the need for them.
