c - Finding strings in the text section -

i have example following code:

foo( "test1" );  void foo(const char* const i_test ) {      // logic } 

the i_test pointer in foo() hold pointer string in .rodata section.

is there way search i_text pointer value in binary file find related string? or can produce debug info using gcc hold info?

if talking elf file format, constant strings stored in .rodata (read-only-data) section. basically, instructions (codes) of program stored in .text section in binary file. can investigate these sections using object dump program (e.g. objdump) following:

objdump -drs program.o           // see .text section of program  objdump -s -j .rodata program.o  // see .rodata section of program 

in sample code above, "test1" string passing foo function treated constant string compiler. thus, can find relative memory address before loading stage , i_test pointer pointing constant string. however, if have compiled code position independent (by using -fpic option in gcc), may find out compiler add writable attribute read-only .rodata section. furthermore, may use readelf binary utility display detailed information elf formatted object file's sections.
