Article
02/22/2024

Searches a string for the last occurrence of a specified character. The comparison is not case-sensitive.

Syntax

PCWSTR StrRChrIW(
  [in]           PCWSTR pszStart,
  [in, optional] PCWSTR pszEnd,
                 WCHAR  wMatch
);

Parameters

[in] pszStart

Type: PTSTR

A pointer to the null-terminated string to be searched.

[in, optional] pszEnd

Type: PCTSTR

A pointer into the source string that defines the range of the search. Set pszEnd to point to a character in the string and the search will stop with the preceding character. Set pszEnd to NULL to search the entire string.

wMatch

Type: TCHAR

The character to search for.

Return value

Type: PTSTR

Returns a pointer to the last occurrence of the character in the string, if successful, or NULL if not.

Remarks

The comparison assumes that pszEnd points to the end of the string.

Note

The shlwapi.h header defines StrRChrI as an alias that automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that is not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
