By emitting an empty function name when it it impossible to perform the lookup, we can get rid of the warning: trace.c:3714: warning: unused variable ‘symbol’ Additionally, this makes the syntax (or, rather, the parameter count) for write-to-png-stream the same on every configuration. |

Cairo Utilities =============== There are a varieties of utilities we use with cairo. backtrace-symbols ----------------- This is a small shared library designed to be preloaded by the linker and its purpose is to make the backtrace_symbols() function of glibc produce more useful source reference information. Build by: make backtrace-symbols.so and use by: LD_PRELOAD=$PWD/backtrace-symbols.so app-to-run This code should be contributed back to glibc at some point. malloc-stats ------------ This is a small shared library designed to be preloaded by the linker and its purpose is to make the malloc_stats() function of glibc produce more useful information. Build by: make malloc-stats.so and use by: LD_PRELOAD=$PWD/malloc-stats.so app-to-run This works best when backtrace-symbols is in use. That is: LD_PRELOAD="$PWD/backtrace-symbols.so $PWD/malloc-stats.so" app-to-run cairo-trace ----------- This tool can be used to trace all the cairo function calls made by an applications. This is useful for either extracting a test case triggering a bug from an application, or simply to get a general idea of how an application is using cairo. cairo-api-update and xr2cairo ----------------------------- These two scripts were used to convert source code written for pre-1.0 cairo to newer API. See $(top_srcdir)/PORTING_GUIDE for more information. These files are obsolete now and may be removed in a future version. cairo-view and waterfall ------------------------ These are two pycairo scripts useful for testing the toy font backend.
