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