From cppreference.com
< cpp | container | forward list

[edit] Parameters
| pos | - | iterator to the element preceding the element to remove |
| first, last | - | range of elements to remove |
[edit] Return value
1) iterator to the element following the erased one, or end() if no such element exists.
2) last
[edit] Complexity
1) Constant.
2) linear in distance between first and last.
[edit] Example
#include <forward_list> #include <iterator> #include <iostream> int main() { std::forward_list<int> l = { 1, 2, 3, 4, 5, 6, 7, 8, 9 }; // l.erase( l.begin() ); // ERROR: No function erase l.erase_after( l.before_begin() ); // Removes first element for( auto n : l ) std::cout << n << " "; std::cout << '\n'; auto fi= std::next( l.begin() ); auto la= std::next( fi, 3 ); l.erase_after( fi, la ); for( auto n : l ) std::cout << n << " "; std::cout << '\n'; }
Output:
2 3 4 5 6 7 8 9 2 3 6 7 8 9
