Why memset is bad?
memset is an example of how blindly following established conventions leads people to doing the wrong thing. One of the most frequent uses for memset is to zero-out memory. The problem with memset is that it’s easy to swap the “value to set” with “count of values to set” arguments.
Is memset faster than for loop?
7 Answers. Most certainly, memset will be much faster than that loop. Note how you treat one character at a time, but those functions are so optimized that set several bytes at a time, even using, when available, MMX and SSE instructions.
Is memset present in C?

Does memset need to be freed?
memset does not allocate memory. It only fills a region of memory with a certain value. You do not have to free the buffer (unless the buffer was allocated).
Is memset faster than memcpy?
zero_sizet is the fastest with roughly equal performance across -O1, -O2 and -O3. memset was always slower than zero_sizet. (twice as slow for -O3). one thing of interest is that at -O3 zero_1 was equally fast as zero_sizet.
Why do we use memset in C?
memset() in C with examples. memset() is used to fill a block of memory with a particular value. The syntax of memset() function is as follows : Note that ptr is a void pointer, so that we can pass any type of pointer to this function.
Why memset is used in C?

Can memset throw?
memset does not throw exceptions.
