Breakpoints
You can set breakpoints either directly in source by navigating to the location and clicking on the line, or by using the At Location dialog.
In this section:
When debugging native Python programs, only standard breakpoints are supported. Barrier points and evalpoints are not available in native Python debugging sessions. For more information, see Set breakpoints in Python code.
If your executable resides in a read-only directory, TotalView may not be able to save your breakpoints. To configure an alternate location to save breakpoint files, see Load and Save Breakpoints for Executables in Read-Only Directories.
