Hi there,
I need to split one huge file into separate files if the condition is fulfilled according to that the position between 97 and 98 matches with “IT” at the segment MAS. There is no delimiter file is fix-width with varous line length.
Could you please help me how I do split the file... (1 Reply)
I am fairly new to HP-UX and trying to get a better understanding of the operating system. While poking around a bit I find myself questioning whether I should be concerned about Shared Memory segments with missing CPID and LPID? For example:

I have created a shared memory segment (which size is 64 bytes) using shmget, shmat e.t.c and i want to divide it into 2 areas. One area for input data and one area for output? How can i do that?
Furthermore, When i have to write my input data into the shared memory segment i want to write... (3 Replies)
Hi,
I wanted to compare EDI files present in Two different Directories which can be related by the file names. While comparing the EDI files i have to skip selected segments such as "ISA" "IEA" and "GS" "GE" since this may have datetime stamp and different "Sender" "Receiver" Qual.

queue(9S) Data Structures for Drivers queue(9S)NAME
queue - STREAMS queue structure
SYNOPSIS
#include <sys/stream.h>
INTERFACE LEVEL
Architecture independent level 1 (DDI/DKI)
DESCRIPTION
A STREAMS driver or module consists of two queue structures, one for upstream processing (read) and one for downstream processing
(write). This structure is the major building block of a stream. It contains pointers to the processing procedures, pointers to the next
and previous queues in the stream, flow control parameters, and a pointer defining the position of its messages on the STREAMS scheduler
list.
The queue structure is defined as type queue_t.
STRUCTURE MEMBERS
struct qinit*q_qinfo; /* module or driver entry points */
struct msgb*q_first; /* first message in queue */
struct msgb*q_last; /* last message in queue */
struct queue*q_next; /* next queue in stream */
struct queue*q_link; /* to next queue for scheduling*/
void *q_ptr; /* pointer to private data structure */
size_t q_count; /* approximate size of message queue */
uint_t q_flag; /* status of queue */
ssize_t q_minpsz; /* smallest packet accepted by QUEUE*/
ssize_t q_maxpsz; /*largest packet accepted by QUEUE */
size_t q_hiwat; /* high water mark */
size_t q_lowat; /* low water mark */
Valid flags are as follows:
QENAB Queue is already enabled to run.
QWANTR Someone wants to read queue.
QWANTW Someone wants to write to queue.
QFULL Queue is considered full.
QREADR This is the reader (first) queue.
QUSE This queue is in use (allocation).
QNOENB Do not enable queue by way of putq().
