Function Documentation

APU_DECLARE

(

int

)

const

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

APU_DECLARE

(

apr_time_t

)

const

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.

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, 6 Nov 94 8:49:37 GMT      ; Unknown [Elm 70.85] 
 

Parameters:

date	The date in one of the 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.
