problem in msgctl() system call
Hi,
i am using IBM P6 server and OS is AIX 5.3. my code is written in c/pro C.
i am facing problem in msgctl() system call.The variables msg_qbytes and msg_cbytes are used to store total no of bytes and current no of bytes in a QUEUE,but it is showing me as ZERO though data are there in QUEUE.
since the same code is working fine in IBM P5 MACHINE, i am quiet surprised.
please help.

euctoibmj
euctoibmj(1) User Commands euctoibmj(1)
NAME
euctoibmj, ibmjtoeuc - Code conversion between Japanese EUC and IBM-Japanese
SYNOPSIS
euctoibmj [-t] [-u code] [-U] [filename...]
ibmjtoeuc [-u code] [-U] [filename...]
AVAILABILITY
SUNWjfpu
DESCRIPTION
euctoibmj converts the contents of the specified filenames from ASCII/ Japanese EUC to EBCDIC/IBM-Japanese. ibmjtoeuc converts the con-
tents of the specified filenames from EBCDIC/IBM-Japanese to ASCII/ Japanese EUC. The both commands write the resultant code to stdout.
If filename is not given, input characters are read from the standard input.
For Japanese language handling, the euctoibmj/ibmjtoeucj pair of commands provide conversion only between the two code standards. Code con-
version among Japanese EUC, JIS, and PC kanji are supported by another set of commands, jistoeuc(1) family or iconv(1).
OPTIONS
-u code With this option specified, characters in one code set that do not have corresponding characters in the other are mapped to the
code given in four-digit hexadecimal HOST CODE of IBM Japanese (for euctoibmj) or in four-digit JIS Ku-Ten code (for ibmjtoeuc).
Without this option, such characters are mapped to HOST CODE 4040 (for euctoibmj) or JIS Ku-Ten code 0101 (for ibmjtoeuc).
-U The output is not buffered (The default is buffered output).
-t With this option specified, euctoibmj translates Half-Size Katakana (Code Set 2) in Japanese EUC to the corresponding characters
in Code Set 1 prior to conversion. Without this option, Code Set 2 characters in Japanese EUC are processed to the illegal charac-
ter.
ENVIRONMENT VARIABLES
The environment variables LC_CTYPE and LANG control the character classification throughout these commands. For euctoibmj and ibmjtoeuc to
work correctly, one or both of the environment variables must be set to ja or an equivalent locale. On entry to these commands, these envi-
ronment variables are checked in the following order: LC_CTYPE and LANG. When a valid value is found, remaining environment variables for
character classification are ignored.

DIAGNOSTICS
unexpected data encountered in input.
Illegal character code is found in input file.
BUGS
The ASCII/EBCDIC conversion table are taken from the 256 character standard in the CACM Nov, 1968. The conversion, while less blessed as
a standard, corresponds better to certain IBM print train convertions. There is no universal solution.
The Japanese EUC/IBM Japanese conversion table is based on the IBM Kanji codebook (4th edition - September 1987), JIS X 0201, and JIS X
0208-1983.
If JIS X 0212 caracter set is specified as input, euctoibmj can not support the conversion correctly.
