You need to be able to read either the executable's symbol table (for a dynamically-linked executable) or its debug information (for an executable with debug info). For a statically-linked executable with no debug info, it's impossible; the function's names simply don't exist anywhere at run-time. I'd suggest looking at the source code for "nm" for details on reading symbol information. -- Glynn Clements <glynn@xxxxxxxxxxxxxxxxxx> - To unsubscribe from this list: send the line "unsubscribe linux-c-programming" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
