function::print_ustack - Linux


The function::print_ustack command prints information about the call stack, including function names, source file paths, and line numbers. It is primarily used for debugging purposes, as it can help identify where errors are occurring in a program.




There are no options or flags available with function::print_ustack.


To print the current call stack, run the following command:



Stack trace:
    function::print_ustack() at /path/to/file.cpp:123
    main() at /path/to/main.cpp:456

Common Issues

One common issue with function::print_ustack is that it can be difficult to read the output if the call stack is very deep. To make the output more readable, you can use the -f option to print only the first few frames of the call stack.

Another issue is that function::print_ustack may not be able to print information for all functions in the call stack. This is because the compiler may not have generated debug information for some functions.


function::print_ustack can be integrated with other debugging tools, such as GDB. By printing the call stack, function::print_ustack can help you identify the location of an error and then use GDB to examine the state of the program at that point.
