StrChrA function

-description

Searches a string for the first occurrence of a character that matches the specified character. The comparison is case-sensitive.

-parameters

-param pszStart [in]

Type: PTSTR

The address of the string to be searched.

-param wMatch

Type: TCHAR

The character to be used for comparison.

-returns

Type: PTSTR

Returns the address of the first occurrence of the character in the string if successful, or NULL otherwise.

-remarks

The comparison assumes pszStart points to the start of a null-terminated string.

Note

The shlwapi.h header defines StrChr as an alias which 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 not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
