POSIX message queues problem..


Hi all,
I am having a weird problem with posix message queues,
i am not at all able to send more than 20 bytes to the message queue, mq_send is failing and telling message too long, but i have set mq_msgsize as 100 bytes and using this attributes in mq_open as

#define MAX_SIZE 100
mqd_t mqdes;
char buff[MAX_SIZE];
struct mq_attr attr;
attr.mq_msgsize = 100;
mqdes = mq_open("/mqueue", O_RDWR | O_CREAT, 644, &attr);

my mq_send is as below

mq_send(mqdes, buff, strlen(buff)+1, 1);
When i set MAX_SIZE as 20 it is sending.. but not more than that... !!!!

Can anyone help me solving this problem...

Thanks
