Initializing the allocated memory is crucial to avoid unpredictable behavior. This can be done in several ways, depending on the needs: Zeroing out memory: Use memset() right after allocation to fill the memory with zeros. Example: int *arr = malloc(10 * sizeof(int)); if (arr != ...

cfg_memset_list is used by cyfitter_cfg() in the PSoC initialization routine to clear these memory areas. The sizes of each of these memory areas are not up to you. These sizes are determined by the PSoC chip you are using. BS_IOPINS0_7_VAL, BS_IOPINS0_1_VAL and BS_IOPINS0_2...
Improved memset unrolling to use SSE2 vector instructions. Improved removal of useless struct/class copies, especially for C++ programs that pass by value. Improved optimization of code usingmemmove, such asstd::copyorstd::vectorandstd::stringconstruction. ...
To test this, we compile the following code that we gave as an example in our article entitled “Connect Function in C language”. This code, although very simple, is very interesting because it connects us to the Google host through the HTTP service and allows us to send the commands and...

An example of everyday code using this technique is the memset function in the C runtime, which should use a code sequence like the above for large blocks. Some architectures provide specialized solutions. The PowerPC architecture defines the dcbz instruction which can be used to clear an ...
