valgrind学习二-suppression

valgrind文档原文

If you're using an error-detection tool, Valgrind may detect errors in system libraries, for example the GNU C or X11 libraries, which you have to use. You might not be interested in these errors, since you probably have no control over that code. Therefore, Valgrind allows you to selectively suppress errors, by recording them in a suppressions file which is read when Valgrind starts up. The build mechanism selects default suppressions which give reasonable behaviour for the OS and libraries detected on your machine. To make it easier to write suppressions, you can use the --gen-suppressions=yes option. This tells Valgrind to print out a suppression for each reported error, which you can then copy into a suppressions file.
