PathRenameExtensionA function

-description

Replaces the extension of a file name with a new extension. If the file name does not contain an extension, the extension will be attached to the end of the string.

Note  Misuse of this function can lead to a buffer overrun. We recommend the use of the safer PathCchRenameExtension function in its place.

 

-parameters

-param pszPath [in, out]

Type: LPTSTR

Pointer to a null-terminated string of length MAX_PATH in which to replace the extension.

-param pszExt [in]

Type: LPCTSTR

Pointer to a character buffer that contains a '.' character followed by the new extension.

-returns

Type: BOOL

Returns nonzero if successful, or zero if the new path and extension would exceed MAX_PATH characters.

-remarks

Note

The shlwapi.h header defines PathRenameExtension 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.
