buffer.h - generic read/write buffering
#include <buffer.h> buffer* buffer_0; /* like stdio's stdin */ buffer* buffer_1; /* like stdio's stdout */ buffer* buffer_2; /* like stdio's stderr */
buffer.h provides a generic buffer interface that can be used for read and write buffering. Buffers must be initialized with buffer_init. A buffer can only be used for reading or writing at the same time, not both. Unlike stdio, these write buffers are not flushed automatically at program termination; you must manually call buffer_flush, buffer_putsflush, buffer_putflush or buffer_putnlflush.
See buffer_init(3) for example read buffer code. Here is typical code for printing an error message on stderr: #include <buffer.h> buffer_puts(buffer_2,"error: got only "); buffer_putulong(buffer_2,got); buffer_puts(buffer_2," bytes, but expected at least "); buffer_putulong(buffer_2,expected); buffer_putsflush(buffer_2," bytes!");
