This causes more test programs to link in the support_record_failure function, which triggers an early call to mmap from an ELF constructor, but this should not have side effects intefering with the functionality actually under test (unlike, say, a call to malloc). |

This subdirectory contains infrastructure which is not put into installed libraries, but may be linked into programs (installed or not) and tests. # Error-checking wrappers These wrappers test for error return codes an terminate the process on error. They are declared in these header files: * support.h * xsignal.h * xthread.h In general, new wrappers should be added to support.h if possible. However, support.h must remain fully compatible with C90 and therefore cannot include headers which use identifers not reserved in C90. If the wrappers need additional types, additional headers such as signal.h need to be introduced. # Test framework The test framework provides a main program for tests, including a timeout for hanging tests. See README-testing.c for a minimal example, and test-driver.c for details how to use it. The following header files provide related declarations: * check.h * temp_file.h * test-driver.h
