Printing an individual ip address in friendly string format . . . I am debugging a network program with gdb IPs are showed as int s, instead of usual IP strings (xxx xxx xxx xxx) Example: (gdb) p addr $1 = {sin_family = 2, sin_port = 2000, sin_addr = {s_addr = 1694542016}, sin_zero = "\000\000\000\000\000\000\000"} At least for doing an individual conversion, I found this 2009 post printing ip addresses using gdb, but in my gdb (recent regular vanilla
Finding the address of an environment variable with and . . . My goal is finding the address of MYVAR outside of GDB, but I cannot tamper with the program, so by replicating the environment inside GDB without the variables set by it I can get the address

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)
