Hi:

This is how I get info from the server. The server sends it in "struct risp" format
Qt Code: 
  1. void MainWindow::getSysStat() {
  2. 	/* create the system info strusture that will hold information about the server */
  3. 	sysInfo = (struct risp *)malloc(sizeof(struct risp));
  4. 	//sysInfo->running_kernel = (char *)malloc(sizeof(char) * LONGEST_KERNEL_NAME);
  5. 	//sysInfo->fsStat->name = (char *)malloc(sizeof(char) * LONGEST_NAME);
  6. 	//sysInfo->fsStat->devName = (char *)malloc(sizeof(char) * LONGEST_NAME);
  7.  
  8. 	/* wait until the socket gets connected */
  9. 	if(socket->waitForConnected(-1)) {
  10. 		/* wait until data gets available */
  11. 		if(socket->waitForReadyRead(-1)) {
  12. 			/* read from the socket */
  13. 			char *dataRead = (char *)malloc(sizeof(char)*sizeof(struct risp));
  14. 			if((socket->read(dataRead, sizeof(struct risp))) == -1)
  15. 				qDebug() << "Error reading data from server";
  16.  
  17. 			/* cast the data to match the risp structure */
  18. 			sysInfo = (struct risp *)dataRead;
  19. 			//qDebug() << "total cpu is: " << sysInfo->total_cpu;
  20. 		}
  21. 	}
  22.  
  23. }
To copy to clipboard, switch view to plain text mode 

Here is struct risp:

Qt Code: 
  1. struct risp {
  2. 	/* cpu info */
  3. 	unsigned long cpu_usage;								/* /proc/ */
  4. 	unsigned long total_cpu;								/* /proc/cpuinfo */
  5. 	//char proc_name[LONGEST_PROC_NAME];				/* /proc/ */
  6. 	//char *cpu_processes[NUMBER_OF_PROCESSES];		/* /proc/ */
  7.  
  8. 	/* ram info */
  9. 	unsigned int ram_usage;					/* /proc/meminfo */
  10. 	unsigned int total_ram;					/* /proc/meminfo */
  11. 	//char *ram_processes[NUMBER_OF_PROCESSES];		/* /proc/ */
  12.  
  13. 	/* swap info */
  14. 	unsigned int swap_usage;					/* /proc/meminfo */
  15. 	unsigned int total_swap;					/* /proc/swaps */
  16.  
  17. 	/* filesystems */
  18. 	struct fsMountList *fsStat;
  19. 	unsigned short int numFs;
  20.  
  21. 	/* kernel info */
  22. 	char *running_kernel;							/* /proc/ */
  23.  
  24. 	float uptime;									/* /proc/uptime -> the first number is the uptime in seconds */
  25. 	unsigned short int num_users;				/* /proc */
  26. 	unsigned short int num_processes;
  27. 	unsigned short int num_running_processes;		/* /proc/stat -> procs_running */
  28. 	char arips_included;							/* 0/1 */
  29.  
  30. };
To copy to clipboard, switch view to plain text mode 


The problem is this:

Qt Code: 
  1. qDebug("Kernel: %s", sysInfo->running_kernel);
To copy to clipboard, switch view to plain text mode 
it displays noting like ti should: it should display: "2.5.25"

So does anybody see what's the problem ?
