read_size

Returns a natural read size.

Synopsis

Defined in header <boost/beast/core/read_size.hpp>

template<
    class DynamicBuffer>
std::size_t
read_size(
    DynamicBuffer& buffer,
    std::size_t max_size);
Description

This function inspects the capacity, size, and maximum size of the dynamic buffer. Then it computes a natural read size given the passed-in upper limit. It favors a read size that does not require a reallocation, subject to a reasonable minimum to avoid tiny reads.

Parameters

Name

Description

buffer

The dynamic buffer to inspect.

max_size

An upper limit on the returned value.

Remarks

If the buffer is already at its maximum size, zero is returned.
