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