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 |
s | - | pointer to a 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.
[edit] Complexity
O(size()
* v.size()
) at worst.
