- c - Display value found at given address gdb - Stack Overflow
I am debugging a binary file in gdb It was C code compiled by gcc on an Intel IA-32 I retrieved this output from objdump I am most interested in the last line here: 08048d9e lt;func_1 gt; 8048
- Debugging with GDB - Examining Data
GDB prints memory addresses showing the location of stack traces, structure values, pointer values, breakpoints, and so forth, even when it also displays the contents of those addresses
- GDB Command Reference - print command - VisualGDB
Previous value number When this format is used and i is specified as the previous value number, the print command will repeat the output produced by its i-th invocation Type Address This format allows explicitly specifying the address of the evaluated expression and can be used as a shortcut to the C C++ type conversion
- Output Formats (Debugging with GDB) - sourceware. org
Output Formats (Debugging with GDB)By default, GDB prints a value according to its data type Sometimes this is not what you want For example, you might want to print a number in hex, or a pointer in decimal Or you might want to view data in memory at a certain address as a character string or as an instruction To do these things, specify an output format when you print a value
- GDB: Print the value of memory address - Stack Overflow
If you want the memory address of variable c, p c would get the addre ss What makes you think that 0x00000000004004 is memory address oc c? That address looks more like memory address of assembly code and 0x85f445c7 represents the hexa representation of machine code
- Debugging with GDB - Print Settings - GNU
If you have a pointer and you are not sure where it points, try `set print symbol-filename on' Then you can determine the name and source file location of the variable where it points, using `p a pointer' This interprets the address in symbolic form For example, here GDB shows that a variable ptt points at another variable t, defined in `hi2 c': (gdb) set print symbol-filename on (gdb) p a
- Can we get address of a variable in a C program using GDB?
Yes, as long as your variable isn’t optimised away For example, using ls with debug symbols: gdb ls >>> break main >>> run >>> print argv $1 = (char **) 0x7fffffffdd78 In this case, argv is a pointer itself If you want the address of a non-pointer variable, or the address of a pointer, use as you would in C; gdb will give you the address, as above, or tell you if the variable isn’t
