rgrover1 0:0b799af9d58e 3 * This file can be used to get extra debugging information about memory leaks in your production code.
rgrover1 0:0b799af9d58e 4 * It defines a preprocessor macro for malloc. This will pass additional information to the
rgrover1 0:0b799af9d58e 5 * malloc and this will give the line/file information of the memory leaks in your code.
rgrover1 0:0b799af9d58e 6 *
rgrover1 0:0b799af9d58e 7 * You can use this by including this file to all your production code. When using gcc, you can use
rgrover1 0:0b799af9d58e 8 * the -include file to do this for you.

rgrover1 0:0b799af9d58e 38 *
rgrover1 0:0b799af9d58e 39 * strdup was implemented earlier, however it is *not* an Standard C function but a POSIX function.
rgrover1 0:0b799af9d58e 40 * Because of that, it can lead to portability issues by providing more than is available on the local platform.
rgrover1 0:0b799af9d58e 41 * For that reason, strdup is *not* implemented as a macro. If you still want to use it, an easy implementation would be:
rgrover1 0:0b799af9d58e 42 *
rgrover1 0:0b799af9d58e 43 * size_t length = 1 + strlen(str);
