You could add static volatile strings in your source code, which would indicate their origins: static char* volatile whence = __FILE__; Then you could a utility like strings (/usr/bin/strings) to find them: strings a.out > Given the executable file only, can we know any way that MYTYPE is a > datatye defined in the .c file? No, not as far as I am aware. (Short of disassembling the source code and reverse engineering it.) That's what the source code and headers are for. Sincerely, --Eljay
