static void assign( char_type& c1, const char_type& c2 );
(1)
(noexcept since C++11)(constexpr since C++17)
static char_type* assign( char_type* ptr, std::size_t count, char_type c2 );
(2)
(constexpr since C++20)
1) Assigns c2 to c1, behaves identically to c1 = c2.
2) Assigns c2 to each character in count characters in the character sequence pointed to by ptr.
See CharTraits for the general requirements on character traits for X::assign.
[edit] Parameters
c1
-
character to assign to
c2
-
character value to assign
ptr
-
pointer to a character sequence to assign to
count
-
the length of the character sequence
[edit] Return value
1) (none)
2) ptr
[edit] Complexity
1) Constant.
2) Linear in count.
