wcsftime(3c) [debian man page]

wcsftime(3C)                                               Standard C Library Functions                                               wcsftime(3C)

NAME

       wcsftime - convert date and time to wide character string

SYNOPSIS

       #include <wchar.h>

   XPG4 and SUS
       size_t wcsftime(wchar_t *wcs, size_t maxsize, const char *format, const struct tm *timptr);

   Default and other standards
       size_t wcsftime(wchar_t *restrict wcs, size_t maxsize, const wchar_t *restrict format, const struct tm *restrict timptr);

DESCRIPTION

       The wcsftime() function is equivalent to the strftime(3C) function, except that:

         o  The argument wcs points to the initial element of an array of wide-characters into which the generated output is to be placed.

         o  The argument maxsize indicates the maximum number of wide-characters to be placed in the output array.

         o  The  argument  format  is  a wide-character string and the conversion specifications are  replaced by corresponding sequences of wide-
            characters.

         o  The return value indicates the number of wide-characters placed in the output array.

       If copying takes place between objects that overlap, the behavior is undefined.

RETURN VALUES

       If the total number of resulting wide character  codes (including the terminating null wide-character code) is no more than maxsize,  wcsf-
       time() returns the number of wide-character codes  placed into the array pointed to by wcs, not including the terminating null wide-charac-
       ter code. Otherwise, 0 is returned and the contents of the array are indeterminate.

       The wcfstime() function uses malloc(3C) and should malloc() fail, errno will be set by malloc().

NOTES

       The wcsftime() function can be used safely in multithreaded applications, as long as setlocale(3C)  is  not  being  called  to  change  the
       locale.

NAME

       mbstowcs - convert a character string to a wide-character string

SYNOPSIS

       #include <stdlib.h>

       size_t mbstowcs(wchar_t *restrict pwcs, const char *restrict s, size_t n);

DESCRIPTION

       The  mbstowcs()	function  converts a sequence of characters from the array pointed to by s into a sequence of corresponding wide-character
       codes and stores not more than n wide-character codes into the array pointed to by pwcs. No characters that follow a null  byte	(which	is
       converted  into	a  wide-character  code  with  value  0)  will	be  examined  or converted. Each character is converted as if by a call to
       mbtowc(3C).

       No more than n elements will be modified in the array pointed to by pwcs. If copying takes place between objects that overlap, the behavior
       is undefined.

       The behavior of this function is affected by the LC_CTYPE category of the current locale. If pwcs is a null pointer, mbstowcs() returns the
       length required to convert the entire array regardless of the value of n, but no values are stored.

RETURN VALUES

       If an invalid character is encountered, mbstowcs() returns (size_t)-1 and may set  errno  to  indicate  the  error.  Otherwise,	mbstowcs()
       returns the number of the array elements modified (or required if pwcs is NULL), not including a terminating 0 code, if any. The array will
       not be zero-terminated if the value returned is n.

ERRORS

       The mbstowcs() function may fail if:

       EILSEQ	       Invalid byte sequence is detected.
