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 this same pool. 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> */ APR_DECLARE(int) apr_vformatter(int (*flush_func)(apr_vformatter_buff_t *b), apr_vformatter_buff_t *c, const char *fmt, va_list ap); /** * Display a prompt and read in the password from stdin. * @param prompt The prompt to display * @param pwbuf Buffer to store the password * @param bufsize The length of the password buffer. * @remark If the password entered must be truncated to fit in * the provided buffer, APR_ENAMETOOLONG will be returned. * Note that the bufsize paramater is passed by reference for no * reason; its value will never be modified by the apr_password_get() * function. */ APR_DECLARE(apr_status_t) apr_password_get(const char *prompt, char *pwbuf, apr_size_t *bufsize); /** @} */ /** * @defgroup apr_ctype ctype functions * These macros allow correct support of 8-bit characters on systems which * support 8-bit characters.
