How to find the address of a string in memory using GDB? If you want to search in the whole address space of the process, you need to get the memory mapping for your process and use the start address the end address with the find command in gdb
Searching Memory (Debugging with GDB) - sourceware. org Searching Memory (Debugging with GDB)If the value size is not specified, it is taken from the value’s type in the current language This is useful when one wants to specify the search pattern as a mixture of types Note that this means, for example, that in the case of C-like languages a search for an untyped 0x42 will search for ‘ (int) 0x42 ’ which is typically four bytes n, maximum
Debugging with GDB - Memory - GNU The default for addr is usually just after the last address examined--but several other commands also set the default address: info breakpoints (to the address of the last breakpoint listed), info line (to the starting address of a line), and print (if you use it to display a value from memory)
Examining Memory With a Debugger - Sonoma State University Fortunately, gdb provides another command for examining the contents of memory directly—that is, the actual bit patterns In order to use this command, we need to determine the actual memory addresses where the anInt and aFloat variables are stored
How to use GDB to find what function a memory address . . . 2 Assuming your binary has debug information g++ -g you may be able to use x to get the info, I know that works for vtables x <num>xw to print <num> hex words of memory, and gdb will annotate the left side with information about what's at the address
Memory (Debugging with GDB) - sourceware. org addr is the address where you want GDB to begin displaying memory The expression need not have a pointer value (though it may); it is always interpreted as an integer address of a byte of memory See Expressions, for more information on expressions
