unsigned char (*main_data)[MAD_BUFFER_MDLEN];  is somewhat equivalent to:

unsigned char **main_data;  

#include <stdio.h>


int main(void)
{
    char (*ptr)[40];

    ptr = malloc(40);

    // some code...
    
    free(ptr);

    return 0;

}

*ptr = (char*)malloc( sizeof(char*) * 40 );

I think this is an array of unsigned char pointers.
