Detailed Description

template<typename SBufT>
class microfmt::sbuf_sink< SBufT >

Output sink that writes formatted characters into a FreeBSD-style sbuf.

Wraps an externally provided sbuf-like pointer and exposes a non-owning, zero-allocation sink interface. Writes are appended safely using the environment's sbuf_bcat function.

By being templated on the buffer type, this class introduces zero hard dependencies on <sys/sbuf.h> unless instantiated.

Template Parameters

SBufT

The opaque buffer struct (typically struct sbuf).

Constructor & Destructor Documentation

sbuf_sink()

template<typename SBufT >

constexpr microfmt::sbuf_sink< SBufT >::sbuf_sink ( SBufT *sb RELOCO_LIFETIMEBOUND  RELOCO_LIFETIME_CAPTURE_BY_THIS )

inlineexplicitconstexprnoexcept

Constructs an sbuf sink over an existing buffer pointer.

Parameters

sb	The target sbuf pointer.

Member Function Documentation

as_sink()

template<typename SBufT >

sink microfmt::sbuf_sink< SBufT >::as_sink ( ) const

inlinenoexcept

Creates a type-erased sink adapter pointing to this instance.

Returns

A lightweight sink struct configured with a callback to append to this sbuf.

native_handle()

template<typename SBufT >

constexpr SBufT * microfmt::sbuf_sink< SBufT >::native_handle ( ) const

inlineconstexprnoexcept

Returns the underlying sbuf pointer.

Returns

The wrapped sbuf instance.
