Get the file extension of a filename.

Function prototype

bool CExtAPI::file_GetExt(ZVAR hStr, const char* lpFileName);


Name Type Comment
hStr ZVAR A ZVAR handle to a string variable to receive the extension string.
lpFileName const char* A handle to a C-style string containing the file name, the extension of which is to be determined.

Return value

False if no extension was found or if an error occurred, and true otherwise (with hStr containing the file extension, without the dot).


Multiple extensions

If a file has multiple extensions, such as 'test.tar.gz', file_GetExt will return the whole extension string (e.g. 'tar.gz'). To get the last extension, call file_GetExt recursively on the file extension until false is returned.


Taken from L3DTio_FI.DLL:


// create a temp var to contain the file extension
ZVAR hStr = theAPI.var_CreateTemp(VarID_string);
if(!hStr) return false;

// get the file extension of lpFileName argument
if(!theAPI.file_GetExt(hStr, lpFileName)) {
    return false;

char FileExt[MAX_PATH]; // declare a char array, into which we'll put the file extension
sprintf(FileExt, "%s", theAPI.str_GetText(hStr));

theAPI.var_Delete(hStr); // done with the temp string var, so delete
