IBM AIX 5.1 routines

[dorth]

i need help finding out what these two aix routines are/do:
local_lock_ppc_mp
local_unlock_ppc_mp

Does anyone have any info on where I can found out what these do?

Thank you.

Why?

Google returns no hits. I doubt the functions are documented
publicly. My hunch is that they're internal to the AIX kernel.

A search of the IBM site for lock_ppc_mp returns a page for an APAR on

IY30798: VSTH 64BIT: GLOBAL_LOCK_PPC_MP() SEGMENTATION FAULT

With the description

Error description
64 bit application core dumps when pthread_cancel is
delivered to another thread.


So I would guess they are internal to the pthread functions.
