strpbrk, wcspbrk, _mbspbrk, _mbspbrk_l

Scans strings for characters in specified character sets.

Important note Important

_mbspbrk and _mbspbrk_l cannot be used in applications that execute in the Windows Runtime. For more information, see CRT functions not supported with /ZW.

str

Null-terminated, searched string.

strCharSet

Null-terminated character set.

locale

Locale to use.

Returns a pointer to the first occurrence of any character from strCharSet in str, or a NULL pointer if the two string arguments have no characters in common.

The strpbrk function returns a pointer to the first occurrence of a character in str that belongs to the set of characters in strCharSet. The search does not include the terminating null character.

wcspbrk and _mbspbrk are wide-character and multibyte-character versions of strpbrk. The arguments and return value of wcspbrk are wide-character strings; those of _mbspbrk are multibyte-character strings.

_mbspbrk validates its parameters. If str or strCharSet is NULL, the invalid parameter handler is invoked, as described in Parameter Validation. If execution is allowed to continue, _mbspbrk returns NULL and sets errno to EINVAL. strpbrk and wcspbrk do not validate their parameters. These three functions behave identically otherwise.

_mbspbrk is similar to _mbscspn except that _mbspbrk returns a pointer rather than a value of type size_t.

In C, these functions take a const pointer for the first argument. In C++, two overloads are available. The overload taking a pointer to const returns a pointer to const; the version that takes a pointer to non-const returns a pointer to non-const. The macro _CONST_CORRECT_OVERLOADS is defined if both the const and non-const versions of these functions are available. If you require the non-const behavior for both C++ overloads, define the symbol _CONST_RETURN.

The output value is affected by the setting of the LC_CTYPE category setting of the locale; for more information, see setlocale. The versions of these functions without the _l suffix use the current locale for this locale-dependent behavior; the version with the _l suffix is identical except that it uses the locale parameter passed in instead. For more information, see Locale.
