Finds the first character not equal to any of the characters in the given character sequence.

1) Finds the first character not equal to any of the characters of v in this view, starting at position pos.

2) Equivalent to find_first_not_of(basic_string_view(&c, 1), pos).

3) Equivalent to find_first_not_of(basic_string_view(s, count), pos).

4) Equivalent to find_first_not_of(basic_string_view(s), pos).

Parameters

v	-	view to search for
pos	-	position at which to start the search
count	-	length of the string of characters to compare
s	-	pointer to a string of characters to compare
ch	-	character to compare

Return value

Position of the first character not equal to any of the characters in the given string, or npos if no such character is found.

Exceptions

1-2)

noexcept specification:

Complexity

O(size() * v.size()) at worst.
