use same library, other result currupt..

i make library, this library function is create circula-queue in shared
memory and attach, queue put, queue get, etc...

sample program make,
1 sample program use library, test make queue in shared memory.
2 sample program use library, test attach queue in shared memory which
created 1 sample program.
result is success.

Then A program use this library, and B program use this library.

A program is create queue in shared memory use library.
B program is attach queue in shared memory which created by A program.
result is shmget fail. - fail reason(Invalid parameter)

so,
ipcs -a typing, and then, not same SEGSZ.
library is always make same size queue in shared memory.

what can i solve this problem??? T^T
