一意のファイル名を作成し、
filenameが指す文字列に格納します。適切な戻り値関数が一意のファイル名のTMP_MAXまで生成することが可能であるが、それらのいくつかまたはすべては、ファイルシステムの使用中であるかもしれないので、しない. Original:
Creates an unique filename and stores it in character string pointed to by
filename. The function is capable of generating up to TMP_MAX of unique filenames, but some or all of them may be in use in the filesystem and thus not suitable return values. The text has been machine-translated via Google Translate.
