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).

[edit] Parameters

v - view to search for
pos - position at which to start the search
count - length of the string of characters to compare

ch - character to compare

[edit] 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.
