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