       The  jstrftime()  function  formats the broken-down jalali time jtm according to the format specification
       format and places the result in the character array s of size max.

       The format specification is a null-terminated string and may contain special character  sequences  called
       conversionspecifications,  each  of which is introduced by a '%' character and terminated by some other
       character known as a  conversionspecifiercharacter.   All  other  character  sequences  are  ordinarycharactersequences.

       The  characters of ordinary character sequences (including the null byte) are copied verbatim from format
       to s. However, the characters of conversion specifications are replaced as follows:

       %a     The abbreviated weekday name.

       %A     The full weekday name.

       %b     The abbreviated month name.

       %B     The full month name.

       %c     The preferred date and time representation.

       %C     The century number (year/100) as a 2-digit integer.

       %d     The day of the month as a decimal number (range 01 to 31).

       %D     Equivalent to %Y/%m/%d.

       %e     Like %d The day of the month as a decimal number, but a leading zero is replaced by a space. (SU)

       %E     The preferred date and time in Farsi. (utf8)

       %F     Equivalent to %Y-%m-%d (similar to the ISO 8601 date format). (C99)

       %h     The abbreviated Farsi transliterated weekday name.

       %q     The full Farsi transliterated weekday name.

       %g     The abbreviated Farsi weekday name. (utf8)

       %G     The full Farsi weekday name. (utf8)

       %v     The abbreviated Farsi month name. (utf8)

       %V     The full Farsi month name. (utf8)

       %H     The hour as a decimal number using a 24-hour clock (range 00 to 23).

       %I     The hour as a decimal number using a 12-hour clock (range 01 to 12).

       %j     The day of the year as a decimal number (range 001 to 366).

       %k     The hour (24-hour clock) as a decimal number (range 0 to 23); single  digits  are  preceded  by  a
              blank.  (See also %H.)  (TZ)

       %l     The  hour  (12-hour  clock)  as  a decimal number (range 1 to 12); single digits are preceded by a
              blank.  (See also %I.)  (TZ)

       %m     The month as a decimal number (range 01 to 12).

       %M     The minute as a decimal number (range 00 to 59).

       %n     A newline character. (SU)

       %O     AM or PM notation for the given time in Farsi equivalent. (utf8)

       %p     Either "AM" or "PM" according to the given time value.  Noon is treated as "PM"  and  midnight  as
              "AM".

       %P     Like %p but in lowercase: "am" or "pm"

       %r     The time in a.m. or p.m. notation.  In the POSIX locale this is equivalent to %I:%M:%S%p.  (SU)

       %R     The time in 24-hour notation (%H:%M). (SU) For a version including the seconds, see %T below.

       %s     The number of seconds since the Epoch, 1970-01-01 (1348-10-11) 00:00:00 +0000 (UTC). (TZ)

       %S     The second as a decimal number (range 00 to 59).

       %t     A tab character. (SU)

       %T     The time in 24-hour notation (%H:%M:%S). (SU)

       %u     The day of the week as a decimal, range 1 to 7, Saturday being 1.  See also %w.  (SU)

       %U     The  week  number of the current year as a decimal number, range 00 to 53, starting with the first
              Sunday as the first day of week 01.

       %w     The day of the week as a decimal, range 0 to 6, Saturday being 0.  See also %u.

       %W     The preferred date in %Y/%m/%d format and Farsi. (utf8)

       %x     The preferred date representation without the time.

       %X     The preferred time representation without the date in Farsi. (utf8)

       %y     The year as a decimal number without a century (range 00 to 99).

       %Y     The year as a decimal number including the century.

       %z     The +hhmm or -hhmm numeric timezone (that is, the hour and minute offset from UTC). (SU)

       %Z     The timezone or name or abbreviation.

       %%     A literal '%' character.

       The broken-down time structure tm is defined in <jtime.h>.  See also jctime(3).

       The environment variables TZ and LC_TIME are used.

   ExampleProgram
       The program below can be used to experiment with jstrftime().

       Some examples of the result string produced  by  the  libjalali  implementation  of  jstrftime()  are  as
       follows:

           $ ./a.out'%m'
           Result string is "11"

       Here's the program source:

       #include <stdio.h>
       #include <stdlib.h>
       #include <time.h>
       #include <jalali.h>
       #include <jtime.h>

       int
       main(int argc, char *argv[])
       {
           char outstr[200];
           time_t t;
           struct tm *tmp;

           t = time(NULL);
           tmp = jlocaltime(&t);
           if (tmp == NULL) {
               perror("jlocaltime");
               exit(EXIT_FAILURE);
           }

           if (jstrftime(outstr, sizeof(outstr), argv[1], tmp) == 0) {
               fprintf(stderr, "jstrftime returned 0");
               exit(EXIT_FAILURE);
           }

           printf("Result string is \"%s\"\n", outstr);
           exit(EXIT_SUCCESS);
       }

       The jstrftime() function returns the number of characters placed  in  the  array  s,  not  including  the
       terminating  null  byte,  provided  the string, including the terminating null byte, fits.  Otherwise, it
       returns max, and the contents of the array is undefined.
