struct logwriter_chan_t
Extends logbuffer_t with isappend mode and log_state_e. If isappend is true the next write to the buffer will be appended even if the buffer is full.

| update | |
| flush_logwriterchan | Flushes logbuffer_t in chan. |
#define logwriter_chan_INIT( size, addr, io, logstate ) { logbuffer_INIT(size, addr, io), 0, logstate, false }
Static initializer.
| size | Size of a temporary or static buffer. |
| addr | Start address of the buffer. |
| io | iochannel_t the buffer is written to. |

Flushes logbuffer_t in chan.

Contains single instance of interface logwriter_it.
Extends logbuffer_t with isappend mode and log_state_e.
struct logwriter_chan_t
Static initializer.

Flushes logbuffer_t in chan.
static void flush_logwriterchan( logwriter_chan_t * chan )
log_it_DECLARE( logwriter_it, logwriter_t )
Contains single instance of interface logwriter_it.
static logwriter_it s_logwriter_interface
Reserves some memory pages for internal buffer.
static int allocatebuffer_logwriter( /*out*/memblock_t * buffer )
Frees internal buffer.
static int freebuffer_logwriter( memblock_t * buffer )
Describes an input/output channel like a file or network connection.
