std::basic_streambuf::pbump

void pbump (int n);
Increase put pointer
Adds n to the put pointer.

The put pointer (pptr) is the internal pointer that points to the current location in the array with the buffered portion of the controlled output sequence.

Parameters

n
Value by which to increase the put pointer.
This shall be a value such that pptr()+n is in the range between pbase and epptr.

Return Value

none

Data races

Modifies the stream buffer object.
Concurrent access to the same stream buffer object may cause data races.

Exception safety

Basic guarantee: if an exception is thrown, the stream buffer is in a valid state.

Invalid arguments cause undefined behavior.
