Can any of you think of other subsets of mmap functionality that are worth supplying a test for in autoconf? Do any of you have time to work on patches for any or all of this?
GraphicsMagick has a GM_FUNC_MMAP_FILEIO macro which does this: This test is derived from GNU Autoconf's similar macro. The purpose of this test is to verify that files may be memory mapped, and that memory mapping and file I/O are coherent. The test creates a test file, memory maps the file, updates the file using the memory map, and then reads the file using file I/O to verify that the file contains the updates. This functionality would be useful in Autoconf if variants are accepted.
