The module command reads debugging information for one or more modules. It is valid only in native mode.
Print the name of the current module.
Read in debugging information for the module called name.
Read in debugging information for all modules.
where:
name is the name of a module for which to read debugging information.
-a specifies all modules.
-f forces reading of debugging information, even if the file is newer than the executable (use with caution!).
-v specifies verbose mode, which prints language, file names, etc.
-q specifies quiet mode.
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:
print *index
