Exceptions are white spaces in the input string +which can match zero or more white space characters in the input string. + +The @code{strptime} function processes the input string from right to +left. Each of the three possible input elements (white space, literal, +or format) are handled one after the other. If the input cannot be +matched to the format string the function stops. The remainder of the +format and input strings are not processed. + +The return value of the function is a pointer to the first character not +processed in this function call. In the case of an error the return +value points to the first character not matched. In case the input +string contains more than required by the format string the return value +points right after the last consumed input character. In case the whole +input string is consumed the return value points to the NUL byte at the +end of the string. +@end deftypefun + +The specification of the function in the XPG standard is rather vague. +It leaves out a few important pieces of information. Most important it +does not specify what happens to those elements of @var{tm} which are +not directly initialized by the different formats. Various +implementations on different Unix systems vary here. + +The GNU libc implementation does not touch those fields which are not +directly initialized. Exceptions are the @code{tm_wday} and +@code{tm_yday} elements which are recomputed if any of the year, month, +or date elements changed. This has two implications: + +@itemize @bullet +@item +Before calling the @code{strptime} function for a new input string one +has to prepare the structure passed in as the @var{tm}. Normally this +will mean that all values are initialized to zero. Alternatively one +can use all fields to values like @code{INT_MAX} which allows to +determine which elements were set by the function call. Zero does not +work here since it is a valid value for many of the fields. + +Careful initialization is necessary if one wants to find out whether a +certain field in @var{tm} was initialized by the function call. + +@item +One can construct a @code{struct tm} value in several @code{strptime} +calls in a row. A useful application of this is for example the parsing +of two separate strings, one containing the date information, the other +the time information. By parsing both one after the other without +clearing the structure in between one can construct a complete +broken-down time. +@end itemize + +The following example shows a function which parses a string which is +supposed to contain the date information in either US style or @w{ISO +8601} form. + +@smallexample +const char * +parse_date (const char *input, struct tm *tm) +@{ + const char *cp; + + /* @r{First clear the result structure.} */ + memset (tm, '\0', sizeof (*tm)); + + /* @r{Try the ISO format first.} */ + cp = strptime (input, "%F", tm); + if (cp == NULL) + @{ + /* @r{Does not match.

The +interface is, mildly said, weird. But if this function fits into the +application to be written it is just fine. It is a problem when using +this function in multi-threaded programs or in libraries since it +returns a pointer to a static variable, uses a global variable, and a +global state (an environment variable). + +@comment time.h +@comment Unix98 +@defvar getdate_err +This variable of type @code{int} will contain the error code of the last +unsuccessful call of the @code{getdate} function. Defined values are: + +@table @math +@item 1 +The environment variable @code{DATEMSK} is not defined or null. +@item 2 +The template file denoted by the @code{DATEMSK} environment variable +cannot be opened. +@item 3 +Information about the template file cannot retrieved. +@item 4 +The template file is no regular file. +@item 5 +An I/O error occurred while reading the template file. +@item 6 +Not enough memory available to execute the function. +@item 7 +The template file contains no matching template. +@item 8 +The input string is invalid for a template which would match otherwise. +This includes error like February 31st, or return values which can be +represented using @code{time_t}. +@end table +@end defvar + +@comment time.h +@comment Unix98 +@deftypefun {struct tm *} getdate (const char *@var{string}) +The interface of the @code{getdate} function is the simplest possible +for a function to parse a string and return the value. @var{string} is +the input string and the result is passed to the user in a statically +allocated variable. + +The details about how the string is processed is hidden from the user. +In fact, it can be outside the control of the program. Which formats +are recognized is controlled by the file named by the environment +variable @code{DATEMSK}. The content of the named file should contain +lines of valid format strings which could be passed to @code{strptime}. + +The @code{getdate} function reads these format strings one after the +other and tries to match the input string. The first line which +completely matches the input string is used. + +Elements which were not initialized through the format string get +assigned the values of the time the @code{getdate} function is called. + +The format elements recognized by @code{getdate} are the same as for +@code{strptime}. See above for an explanation. There are only a few +extension to the @code{strptime} behavior: + +@itemize @bullet +@item +If the @code{%Z} format is given the broken-down time is based on the +current time in the timezone matched, not in the current timezone of the +runtime environment. + +@emph{Note}: This is not implemented (currently). The problem is that +timezone names are not unique. If a fixed timezone is assumed for a +given string (say @code{EST} meaning US East Coast time) uses for +countries other than the USA will fail. So far we have found no good +solution for this. + +@item +If only the weekday is specified the selected day depends on the current +date. If the current weekday is greater or equal to the @code{tm_wday} +value this weeks day is selected. Otherwise next weeks day. + +@item +A similar heuristic is used if only the month is given, not the year. +For value corresponding to the current or a later month the current year +s used. Otherwise the next year. The first day of the month is assumed +if it is not explicitly specified. + +@item +The current hour, minute, and second is used if the appropriate value is +not set through the format. + +@item +If no date is given the date for the next day is used if the time is +smaller than the current time. Otherwise it is the same day. +@end itemize + +It should be noted that the format in the template file need not only +contain format elements.
