How to return an array of structure from a dll function?

I am trying to get structure array output from a function in dll. A structure named ascmsg_struct is defined in the header file getasc.h as follows:

struct ascmsg_struct{
    double raw_time;
    unsigned int channel;
    char msg_id[9];
    char msg_data[17];
};
#define NO_OF_MSG 2000

A function named readAsc is defined in the readAsc.c file as follows:

int readAsc(struct ascmsg_struct* myArray)
  {
      int msg_idx=0;
      FILE *file;
      char line[256];

        //Open file
        file = fopen("TestFile.asc", "r");

        if (!file)
            {
            fprintf(stderr, "Unable to open file.");
            return EXIT_FAILURE;
            }

        while (fgets(line, sizeof(line), file) && msg_idx<NO_OF_MSG) 
        {
            if(strstr(line, "Rx ") != NULL)
            {
            myArray[msg_idx]=process_line(line);
            msg_idx++;
            }
        }
        fclose(file);

        return EXIT_SUCCESS;
    }

Also function process_line is defined as follows:

struct ascmsg_struct process_line(char line[256])
{
    struct ascmsg_struct outstruct= {0, 0, "", ""};

      // After some processing prepare outstruct
      outstruct.raw_time = 0.0;
      outstruct.channel = 0;
      strncpy(outstruct.msg_id,"12345678",8);
      strncpy(outstruct.msg_data,"1122334455667788",16);

      return outstruct;
  }

A global variable holding array of structure is defined as follows:

struct ascmsg_struct myArray[NO_OF_MSG];

In the main function it is used as follows:

struct ascmsg_struct* ptr=NULL;    
ptr=&myArray[0];

and later...

if(readAsc(ptr)==EXIT_SUCCESS)
        printf("Asc read = SUCCESS\n");

After doing this I have my intended structure array in myArray[NO_OF_MSG].

I have generated dll and I would like to output myArray[NO_OF_MSG] to matlab. How do I do that?

People are saying matlab does not handle structure from dll very well ans some are saying it is supported. Please see this .

After generating dll, I am trying this:

[notfound,warnings]=loadlibrary('readasc.dll','readasc.h');
sp=libpointer('ascmsg_structPtr');
calllib('libreadasc', 'readFullAsc',sp); <--This causes matlab to crash. I believe some pointer issue.

What am I doing wrong? Any help is greatly appreciated.

Many Thanks,
