77 * Now you have 3 ways for the malloc function:
\r
79 * 1. Do not change anything, use the original malloc
\r
81 * 2. Use the clear_malloc function instead of the original malloc.
\r
82 * In this case you must use the following define:
\r
83 * #define malloc((_a)) clear_malloc((_a))
\r
85 * 3. Use the fill_malloc function instead of the original malloc.
\r
86 * In this case you must use the following define:
\r
87 * #define malloc((_a)) fill_malloc((_a))
\r
89 * We have figured out that there could exist some malloc problems
\r
90 * where variables are using without to be initialise. To find this
\r
91 * places, use the fill_malloc function. With this function we want
\r
92 * to initialize memory to some known bad state. This is quite easily
\r
93 * spotted in the debugger and will trap to an invalid address.
\r
95 * clear_malloc can be used if you want to set not initialise
\r
98 * If you do not want to change the malloc function, to not use one of
\r
99 * the following macros. Which is the default way.
