#define AUX_BUF_SIZE (5*512) System aux memory buffer size.System data buffers.
System gives access to two memory blocks (Auxiliary buffer and write buffer) for temporary use by program. Mainly to avoid repeated use of memory allocation and avoid possibility of not available memory.
Auxiliary buffer is always available.
Write buffer is shared with system for disk write operations. Therefore data in this buffer can be overwritten by disk write operations. User can use sys_clear_write_buf_used() and sys_write_buf_used() functions to clear and check write buffer used flag. User should also avoid to use this buffer if disk write mode is enabled (see sys_disk_write_enable() ).
◆ aux_buf_ptr()Get pointer to aux memory buffer.
Get 'write-buffer-used' flag.
This flag is se by any disk write operation which uses write buffer.
◆ write_buf_ptr()Get pointer to write buffer.
Get write buffer size.
