Read-only data segments typically occur when an application memory maps a database. For example:
caddr_t vaddr = NULL; off_t offset = 0; size_t = 10 * 1024; int fd; fd = open("../DATABASE", ...) vaddr = mmap(vaddr, size, PROT_READ, MAP_SHARED, fd, offset); index = (DBIndex *) vaddr;
To be able to access the database through the debugger as memory you would type:
mmapfile ../DATABASE $[vaddr] $[offset] $[size]
Then you could look at your database contents in a structured way by typing:
