String manipulation routines operate on null-terminated single-byte character and wide-character strings. Use the buffer-manipulation routines, described in Buffer Manipulation, to work with character arrays that do not end with a null character.

Generally, Windows Embedded CE supports wide-character versions of functions rather than other versions. This enables Windows Embedded CE to support Unicode while keeping the library compact.

Routine	Use
sprintf, swprintf	Writes formatted data to a string. These functions have been deprecated because more secure versions are available.
sprintf_s, swprintf_s	Writes formatted data to a string. Security-enhanced versions of deprecated functions sprintf and swprintf. Windows Embedded CE 6.0 does not support forms of this function that use the Locale parameter, sprintf_s_l, and swprintf_s_l.
strcat, wcscat	Appends one string to another. These functions have been deprecated because more secure versions are available.
strcat_s, wsccat_s	Appends a string. Security-enhanced versions of deprecated functions strcat and wcscat. Template overload available. Windows Embedded CE 6.0 does not support the multibyte form of this function, _mbscat_s.
strchr, wcschr	Finds first occurrence of specified character in string
strcmp, wcscmp	Compares two strings
strcpy, wcscpy	Copies one string to another. These functions have been deprecated because more secure versions are available.
strcpy_s, wcscpy_s	Copies a string. Security-enhanced versions of deprecated functions strcpy and wcscpy. Buffers require NULL termination and should assert on truncation. Template overload available. Windows Embedded CE 6.0 does not support the multibyte form of this function, _mbscpy_s.
strcspn, wcscspn	Finds first occurrence of character from specified character set in string
_strdup, _wcsdup	Duplicates string
_stricmp, _wcsicmp	Compares two strings without regard to case
strlen, wcslen	Finds length of string. These functions have been deprecated because more secure versions are available.
strnlen, wcsnlen	Gets the length of a string, using the current locale or one that has been passed in. More secure than previous versions of strlen and wcslen. Windows Embedded CE 6.0 does not support the multibyte forms of this function or forms that use the Locale parameter, strnlen_s_l, _mbsnlen_s, _mbsnlen_s_l and _wcsnlen_s_l.
_strlwr, _wcslwr	Converts string to lowercase. These functions have been deprecated because more secure versions are available.
_strlwr_s, _wcslwr_s	Converts a string to lowercase, using the current locale or a locale object passed in. Security-enhanced versions of deprecated function _strlwr and _wcslwr. Windows Embedded CE 6.0 does not support the multibyte forms of this function or forms of this function that use the Locale parameter, _mbslwr_s,
strncat, wcsncat	Appends characters of string. These functions have been deprecated because more secure versions are available.
strncat_s, wcsncat_s	Appends characters to a string. Security-enhanced versions of deprecated functions strncat and wcsncat. Validates parameters, template overload available. Windows Embedded CE 6.0 does not support the multibyte forms of this function or forms that use the Locale parameter, strncat_s_l, _mbsncat_s, _mbsncat_s_l and _wcsncat_s_l.
strncmp, wcsncmp	Compares characters of two strings
strncpy, wcsncpy	Copies characters of one string to another. These functions have been deprecated because more secure versions are available.
strncpy_s, wcsncpy_s	Copies characters of one string to another. Security-enhanced versions of deprecated functions strncpy and wcsncpy. Template overload available. Windows Embedded CE 6.0 does not support the multibyte forms of this function or forms that use the Locale parameter, strncpy_s_l, _mbsncpy_s, _mbsncpy_s_l and _wcsncpy_s_l.
_strnicmp, _wcsnicmp	Compares characters of two strings without regard to case
_strnset, _wcsnset	Sets first n characters of string to specified character. These functions have been deprecated because more secure versions are available.
_strnset_s, _wcsnset_s	Initializes characters of a string to a given character. Security-enhanced versions of deprecated functions _strnset and _wcsnet. Windows Embedded CE 6.0 does not support the multibyte forms of this function or forms that use the Locale parameter, strnset_s_l, _mbsnset_s, _mbsnset_s_l and _wcsnset_s_l.
strpbrk, wcspbrk	Finds first occurrence of character from one string in another string
strrchr, wcsrchr	Finds last occurrence of given character in string
_strrev, _wcsrev	Reverses string
_strset, _wcsset	Sets all characters of string to specified character. These functions have been deprecated because more secure versions are available.
_strset_s, _wcsset_s	Sets characters of a string to a character. Security-enhanced versions of deprecated functions _strset and _wcsset. Windows Embedded CE 6.0 does not support the multibyte forms of this function or forms that use the Locale parameter, strset_s_l, _mbsset_s, _mbsset_s_l and _wcsset_s_l.
strspn, wcsspn	Finds first substring from one string in another string
strstr, wcsstr	Finds first occurrence of specified string in another string
strtod, wcstod	Converts to double-precision value
strtok, wcstok	Finds next token in string. These functions have been deprecated because more secure versions are available.
strtok_s, wcstok_s	Finds the next token in a string, using the current locale or a locale passed in. Security-enhanced versions of deprecated functions strtok and wcstok. Windows Embedded CE 6.0 does not support the multibyte forms of this function or forms that use the Locale parameter, strtok_s_l, _mbstok_s, _mbstok_s_l and _wcstok_s_l.
strtol, wcstol	Converts to long integer value
strtoul, wcstoul	Converts to unsigned long integer value
_strupr, _wcsupr	Converts string to uppercase. These functions have been deprecated because more secure versions are available.
_strupr_s, _wcsupr_s	Converts a string to uppercase, using the current locale or a specified locale passed in. Security-enhanced versions of deprecated functions _strup and _wcsrup.
