Hi RudiC.
If you look at position 33, there are 3 different types of segments (UK, UX, CU).
That's why we cannot process the source file as is since each segment can have different data lengths.
We need to split the source file by segment types first and then process each sub file separately.
I hope I answered your question.
Thanks.

LEARN ABOUT OPENSOLARIS
plock
plock(3C) Standard C Library Functions plock(3C)
NAME
plock - lock or unlock into memory process, text, or data
SYNOPSIS
#include <sys/lock.h>
int plock(int op);
DESCRIPTION
The plock() function allows the calling process to lock or unlock into memory its text segment (text lock), its data segment (data lock),
or both its text and data segments (process lock). Locked segments are immune to all routine swapping. The effective user ID of the calling
process must be super-user to use this call.
The plock() function performs the function specified by op:
PROCLOCK Lock text and data segments into memory (process lock).
TXTLOCK Lock text segment into memory (text lock).
DATLOCK Lock data segment into memory (data lock).
UNLOCK Remove locks.
RETURN VALUES
Upon successful completion, 0 is returned. Otherwise, -1 is returned and errno is set to indicate the error.
ERRORS
The plock() function fails and does not perform the requested operation if:
EAGAIN Not enough memory.
EINVAL The op argument is equal to PROCLOCK and a process lock, a text lock, or a data lock already exists on the calling process; the
op argument is equal to TXTLOCK and a text lock or a process lock already exists on the calling process; the op argument is equal
to DATLOCK and a data lock or a process lock already exists on the calling process; or the op argument is equal to UNLOCK and no
lock exists on the calling process.
EPERM The {PRIV_PROC_LOCK_MEMORY} privilege is not asserted in the effective set of the calling process.
USAGE
The mlock(3C) and mlockall(3C) functions are the preferred interfaces for process locking.
