- * apr_vformatter() is a generic printf-style formatting routine
- * with some extensions.
- * @param flush_func The function to call when the buffer is full
- * @param c The buffer to write to
- * @param fmt The format string
- * @param ap The arguments to use to fill out the format string.
- *
- * @remark
- * <PRE>
- * The extensions are:
- *
- * %%pA takes a struct in_addr *, and prints it as a.b.c.d
- * %%pI takes an apr_sockaddr_t * and prints it as a.b.c.d:port or
- * [ipv6-address]:port
- * %%pT takes an apr_os_thread_t * and prints it in decimal
- * ('0' is printed if !APR_HAS_THREADS)
- * %%pp takes a void * and outputs it in hex
- *
- * The %%p hacks are to force gcc's printf warning code to skip
- * over a pointer argument without complaining. This does
- * mean that the ANSI-style %%p (output a void * in hex format) won't
- * work as expected at all, but that seems to be a fair trade-off
- * for the increased robustness of having printf-warnings work.
- *
- * Additionally, apr_vformatter allows for arbitrary output methods
- * using the apr_vformatter_buff and flush_func.
- *
- * The apr_vformatter_buff has two elements curpos and endpos.
- * curpos is where apr_vformatter will write the next byte of output.
- * It proceeds writing output to curpos, and updating curpos, until
- * either the end of output is reached, or curpos == endpos (i.e. the
- * buffer is full).
- *
- * If the end of output is reached, apr_vformatter returns the
- * number of bytes written.
- *
- * When the buffer is full, the flush_func is called. The flush_func
- * can return -1 to indicate that no further output should be attempted,
- * and apr_vformatter will return immediately with -1. Otherwise
- * the flush_func should flush the buffer in whatever manner is
- * appropriate, re apr_pool_t nitialize curpos and endpos, and return 0.
- *
- * Note that flush_func is only invoked as a result of attempting to
- * write another byte at curpos when curpos >= endpos. So for
- * example, it's possible when the output exactly matches the buffer
- * space available that curpos == endpos will be true when
- * apr_vformatter returns.
- *
- * apr_vformatter does not call out to any other code, it is entirely
- * self-contained. This allows the callers to do things which are
- * otherwise "unsafe". For example, apr_psprintf uses the "scratch"
- * space at the unallocated end of a block, and doesn't actually
- * complete the allocation until apr_vformatter returns. apr_psprintf
- * would be completely broken if apr_vformatter were to call anything
- * that used a apr_pool_t. Similarly http_bprintf() uses the "scratch"
- * space at the end of its output buffer, and doesn't actually note
- * that the space is in use until it either has to flush the buffer
- * or until apr_vformatter returns.
- * </PRE>
