This directory contains example programs for the user to experiment with. Initially there is one application written in C. The plan is to include more examples, also in other langauges, over time. In addition to the sources and a make file, a sample script how to make a profile is included. There is also a README.md file. gprofng/ChangeLog 2024-01-08 Ruud van der Pas <ruud.vanderpas@oracle.com> * examples: Top level directory. * examples/mxv-pthreads: Example program written in C.
