std::messages<CharT>::~messages – std::messages<CharT>::~messages Synopsis Defined in header <locale> protected: ~messages(); Destructs a std::messages facet. This destructor is protected and virtual (due to base_class destructor being virtual). An object of type std::messages, like most facets, can only be destroyed when the last std::locale object that implements this facet goes out of scope or if a user-defined…

std::memcpy – std::memcpy Synopsis Defined in header<cstring> void *memcpy(void *dest, const void *src, std::size_t count); Copies count bytes from the object pointed to by src to the object pointed to by dest. Both objects are reinterpreted as arrays of unsigned char. If the objects overlap, the behavior is undefined. If either dest or src is…

std::memcmp – std::memcmp Synopsis Defined in header<cstring> int memcmp(const void *lhs, const void *rhs, std::size_t count); Reinterprets the objects pointed to by lhs and rhs as arrays of unsigned char and compares the first count characters of these arrays.

std::memchr – std::memchr Synopsis Defined in header<cstring> const void *memchr(const void *ptr, int ch, std::size_t count); void *memchr(void *ptr, int ch, std::size_t count); Converts ch to unsigned char and locates the first occurrence of that value in the initial count characters (each interpreted as unsigned char) of the object pointed to by ptr. This function…
