Hello,
In shared memory, when using shmget function, first parameter is ket_t key.
I know it is an integer type, but length of it is system dependent. That means may not be have integer's ranges.
What is range of key_t in Linux? Is it different in distros, for example in ubuntu & fedora? (2 Replies)

if suppose max length is 2,
then compare the all records if <2 then add zero's prefix of the record.

adjmsg(9F) Kernel Functions for Drivers adjmsg(9F)NAME
adjmsg - trim bytes from a message
SYNOPSIS
#include <sys/stream.h>
int adjmsg(mblk_t *mp, ssize_t len);
INTERFACE LEVEL
Architecture independent level 1 (DDI/DKI).
PARAMETERS
mp Pointer to the message to be trimmed.
len The number of bytes to be removed.
DESCRIPTION
The adjmsg() function removes bytes from a message. |len| (the absolute value of len) specifies the number of bytes to be removed. The
adjmsg() function only trims bytes across message blocks of the same type.
The adjmsg() function finds the maximal leading sequence of message blocks of the same type as that of mp and starts removing bytes either
from the head of that sequence or from the tail of that sequence. If len is greater than 0, adjmsg() removes bytes from the start of the
first message block in that sequence. If len is less than 0, it removes bytes from the end of the last message block in that sequence.
The adjmsg() function fails if |len| is greater than the number of bytes in the maximal leading sequence it finds.
The adjmsg() function may remove any except the first zero-length message block created during adjusting. It may also remove any zero-
length message blocks that occur within the scope of |len|.
RETURN VALUES
The adjmsg() function returns:
1 Successful completion.
0 An error occurred.
CONTEXT
The adjmsg() function can be called from user or interrupt context.
