| Zusammenfassung: | A computer system is provided with memory divided by the operating system into kernel space and user space. A probe function is provided in a related user-space application to support dynamic insertion of instrumentation into the application. A breakpoint instruction is provided in an area of the process's user space that will not be overwritten to support execution of an instrumentation subroutine when a probed subroutine in the application returns. |
