Subject: query...
Hi,
I am Creating a posix message queue using the following code.
#include <stdio.h>
#include <stdlib.h>
#include <mqueue.h>
#include <errno.h>
#include <string.h>
#include <fcntl.h>
#include <sys/stat.h>
#include <sys/types.h>
int main(int argc,char *argv[])
{
mqd_t mq_des;
mq_des = mq_open(argv[1],O_CREAT | O_RDWR | O_EXCL,S_IRUSR | S_IWUSR
| S_IRGRP | S_IROTH , NULL);
if(mq_des < 0)
{
printf("Unable To Create MsgQ\n");
perror("mq_open");
return mq_des;
}
printf("MsgQ is Opened With Descriptor : %d\n",mq_des);
return mq_des;
}
and I after compiling I am giving
./a.out /root/Desktop/msgq1
But It is giving as unable to create message queue and showing error as
'permission denied'
Would you please help me.
