101 * Now you have 3 ways for the malloc function:
103 * 1. Do not change anything, use the original malloc
105 * 2. Use the clear_malloc function instead of the original malloc.
106 * In this case you must use the following define:
107 * #define malloc((_a)) clear_malloc((_a))
109 * 3. Use the fill_malloc function instead of the original malloc.
110 * In this case you must use the following define:
111 * #define malloc((_a)) fill_malloc((_a))
113 * We have figured out that there could exist some malloc problems
114 * where variables are using without to be initialise. To find this
115 * places, use the fill_malloc function. With this function we want
116 * to initialize memory to some known bad state. This is quite easily
117 * spotted in the debugger and will trap to an invalid address.
119 * clear_malloc can be used if you want to set not initialise
122 * If you do not want to change the malloc function, to not use one of
123 * the following macros. Which is the default way.
