std::basic_streambuf<CharT,Traits>::gbump - cppreference.com (original) (raw)
| protected: void gbump( int count ); | | | | ----------------------------------- | | |
Skips count characters in the get area. This is done by adding count to the get pointer. No checks are done for underflow.
[edit] Parameters
| count | - | number of characters to skip |
|---|
[edit] Return value
(none)
[edit] Notes
Because this function takes an int, it cannot manipulate buffers larger than std::numeric_limits<int>::max() characters (LWG issue 255).
