How do I filter a long report, with the "STARTWORD" and "STOPWORD" as the variables to use in my awk command, to print the whole data segment that only contains the matched start/stop word?
awk '/start/, /stop/' file <- this prints the line, though I need to print the whole segment. Newline... (1 Reply)

Hi guys,
Are all users authorised to modify the data segment and stack segment to unlimited on AIX?
Is a reboot required after giving ulimit -d unlimited?
Thanks

Hi guys,
I use AIX version 5 on IBM Power 5+ machine. I am currently trying to experiment with sort of self-modifying code, like this:

int iar = ut.uc_mcontext.jmp_context.iar;
int pageSize = getpagesize();
int rest = iar % pageSize;

plock
plock(2) System Calls Manual plock(2)Name
plock - lock or unlock process, text, or data in memory
Syntax
#include <sys/lock.h>
int plock (op)
int op;
Description
The call allows the calling process to lock its text segment (text lock), its data segment (data lock), or both its text and data segments
(process lock) into memory. Locked segments are immune to page outs, and the process is immune to swap outs. The call also unlocks these
segments.
The op argument specifies the following:
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, a value of 0 is returned to the calling process. Otherwise, a value of -1 is returned, and errno is set to
indicate the error.
Diagnostics
The call fails under the following conditions:
[EPERM] The effective user ID of the calling process is not superuser.
[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.
[EINVAL] The op argument is equal to TXTLOCK, and a text lock or a process lock already exists on the calling process.
[EINVAL] The op argument is equal to DATLOCK, and a data lock or a process lock already exists on the calling process.
[EINVAL] The op argument is equal to UNLOCK, and no type of lock exists on the calling process.
Restrictions
The effective user ID of the calling process must be superuser to use this call.
Both PROCLOCK and TXTLOCK lock the text segment of a process, and a locked text segment is locked for all sharing processes.
Because the effective user ID of the calling process is superuser, take care not to lock more virtual pages than can be contained in physi-
cal memory. A deadlock can result.
