16.8. Memory Block HandlingThe functions listed in Table 16-21 initialize, copy, search, and compare blocks of memory. The functions declared in the header string.h access a memory block byte by byte, while those declared in wchar.h read and write units of the type wchar_t. Accordingly, the size parameter of each function indicates the size of a memory block as a number of bytes, or as a number of wide characters.
