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(). ATTRIBUTES

The wcsftime() function can be used safely in multithreaded applications, as long as setlocale(3C) is not being called to change the locale. SunOS 5.10 1 Nov 2003 wcsftime(3C)

wcsxfrm(3C) Standard C Library Functions wcsxfrm(3C) NAME
wcsxfrm, wsxfrm - wide character string transformation SYNOPSIS
#include <wchar.h> size_t wcsxfrm(wchar_t *ws1, const wchar_t *ws2, size_t n); size_t wsxfrm(wchar_t *ws1, const wchar_t *ws2, size_t n); DESCRIPTION
The wcsxfrm() and wcsxfrm() functions transform the wide character string pointed to by ws2 and place the resulting wide character string into the array pointed to by ws1. The transformation is such that if either the wcscmp(3C) or wscmp(3C) functions are applied to two trans- formed wide strings, they return a value greater than, equal to, or less than 0, corresponding to the result of the wcscoll(3C) or wscoll(3C) function applied to the same two original wide character strings. No more than n wide-character codes are placed into the resulting array pointed to by ws1, including the terminating null wide-character code. If n is 0, ws1 is permitted to be a null pointer. If copying takes place between objects that overlap, the behavior is undefined. The wcsxfrm() and wsxfrm() functions do not change the setting of errno if successful. Since no return value is reserved to indicate an error, an application wishing to check for error situations should set errno to 0, then call wcsxfrm() or wsxfrm(), then check errno. RETURN VALUES
The wcsxfrm() and wsxfrm() functions return the length of the transformed wide character string (not including the terminating null wide- character code). If the value returned is n or more, the contents of the array pointed to by ws1 are indeterminate. On error, wcsxfrm() and wsxfrm() may set errno but no return value is reserved to indicate an error. ERRORS
The wcsxfrm() and wsxfrm() functions may fail if: EINVAL The wide character string pointed to by ws2 contains wide-character codes outside the domain of the collating sequence. USAGE
The transformation function is such that two transformed wide character strings can be ordered by the wcscmp() or wscmp() functions as appropriate to collating sequence information in the program's locale (category LC_COLLATE). The fact that when n is 0, ws1 is permitted to be a null pointer, is useful to determine the size of the ws1 array prior to making the transformation. ATTRIBUTES
