Allows you to cause malloc to fail.
git clone git://github.com/jbboehr/covmalloc.git
cd covmalloc
./configure && make installYou'll need to link the module to use covmalloc_failure, and you'll also need to run your tests using LD_PRELOAD. For example, with automake:
TESTS_ENVIRONMENT += LD_PRELOAD=@LIBCOVMALLOC_DIR@/libcovmalloc.so
AM_LDFLAGS = @COVMALLOC_LIBS@
Example:
int * a, int * b, int * c;
a = malloc(sizeof(int)); // ok
covmalloc_failure(1);
b = malloc(sizeof(int)); // NULL
covmalloc_failure(0);
c = malloc(sizeof(int)); // okThis project is licensed under the MIT license.
