AP_DECLARE (  apr_status_t   )

convert a recent time to its human readable components in local timezone Parameters: tm  the exploded time t  the time to explode: MUST be within the last AP_TIME_RECENT_THRESHOLD seconds Note: This is a faster alternative to apr_explode_localtime that uses a cache of pre-exploded time structures. It is useful for things that need to explode the current time multiple times per second, like loggers. Returns: APR_SUCCESS iff successful Definition at line 203 of file protocol.c.

AP_DECLARE (  apr_time_t   )

Definition at line 162 of file protocol.c. References AP_DECLARE, and now.

AP_DECLARE (  void   )

Send the minimal part of an HTTP response header. Parameters: r  The current request bb  The brigade to add the header to. Warning: Modules should be very careful about using this, and should the default behavior. Much of the HTTP/1.1 implementation correctness depends on the full headers. void ap_basic_http_header(request_rec *r, apr_bucket_brigade *bb) Definition at line 80 of file protocol.c. References AP_DECLARE, and NULL.

AP_DECLARE_NONSTD (  int   )

Read headers strings from a script, ensuring that the output is valid. If the output is valid, then the headers are added to the headers out of the current request Parameters: r  The current request buffer  Empty when calling the function. On output, if there was an error, the string that cause the error is stored here. termch  Pointer to the last character parsed. termarg  Pointer to an int to capture the last argument parsed. args  String arguments to parse consecutively for headers, a NULL argument terminates the list. Returns: HTTP_OK on success, HTTP_INTERNAL_SERVER_ERROR otherwise int ap_scan_script_header_err_core(request_rec *r, char *buffer, int (*getsfunc)(char *, int, void *), void *getsfunc_data) Definition at line 1452 of file protocol.c.
