Define Documentation

#define APR_DATE_BAD   ((apr_time_t)0)
 

A bad date.


Function Documentation

int apr_date_checkmask const char *  data,
const char *  mask
 

Compare a string to a mask

Parameters:
data The string to compare
mask Mask characters (arbitrary maximum is 256 characters):
'@' - uppercase letter '$' - lowercase letter '&' - hex digit '#' - digit '~' - digit or space '*' - swallow remaining characters
Remarks:
The mask tests for an exact match for any other character
Returns:
1 if the string matches, 0 otherwise

apr_time_t apr_date_parse_http const char *  date  ) 
 

Parses an HTTP date in one of three standard forms:

Sun, 06 Nov 1994 08:49:37 GMT ; RFC 822, updated by RFC 1123 Sunday, 06-Nov-94 08:49:37 GMT ; RFC 850, obsoleted by RFC 1036 Sun Nov 6 08:49:37 1994 ; ANSI C's asctime() format
Parameters:
date The date in one of the three formats above
Returns:
the apr_time_t number of microseconds since 1 Jan 1970 GMT, or 0 if this would be out of range or if the date is invalid.

apr_time_t apr_date_parse_rfc const char *  date  ) 
 

Parses a string resembling an RFC 822 date. This is meant to be leinent in its parsing of dates. Hence, this will parse a wider range of dates than apr_date_parse_http.

The prominent mailer (or poster, if mailer is unknown) that has been seen in the wild is included for the unknown formats.

Sun, 06 Nov 1994 08:49:37 GMT ; RFC 822, updated by RFC 1123 Sunday, 06-Nov-94 08:49:37 GMT ; RFC 850, obsoleted by RFC 1036 Sun Nov 6 08:49:37 1994 ; ANSI C's asctime() format Sun, 6 Nov 1994 08:49:37 GMT ; RFC 822, updated by RFC 1123 Sun, 06 Nov 94 08:49:37 GMT ; RFC 822 Sun, 6 Nov 94 08:49:37 GMT ; RFC 822 Sun, 06 Nov 94 08:49 GMT ; Unknown [drtr@ast.cam.ac.uk] Sun, 6 Nov 94 08:49 GMT ; Unknown [drtr@ast.cam.ac.uk] Sun, 06 Nov 94 8:49:37 GMT ; Unknown [Elm 70.85] Sun, 6 Nov 94 8:49:37 GMT ; Unknown [Elm 70.85]
