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