Subject: New macro (DONT_USE_MMAP) to support testing as if mmap() is unavailable
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=f76d4727548372a40337fd2e9aed558f6ebadf83;p=libatomic_ops

New macro (DONT_USE_MMAP) to support testing as if mmap() is unavailable

* src/atomic_ops_malloc.c [DONT_USE_MMAP] (HAVE_MMAP): Undefine (after
including config.h).
* tests/test_malloc.c [DONT_USE_MMAP] (HAVE_MMAP): Likewise.
