Can include a full path andwildcards (* and ?).buffer(Output) Derived type FILE$INFO or derived type FILE$INFOI8. Information about a file thatmatches the search criteria in files. The derived type FILE$INFO is defined in IFPORT.F90 asfollows:TYPE FILE$INFOINTEGER(4) CREATION! CREATION TIME (-1 ON FAT)INTEGER(4) LASTWRITE! LAST WRITE TO FILEINTEGER(4) LASTACCESS!

FILE NAME(Input; output) INTEGER(4) on IA-32 processors; INTEGER(8) on Intel Itanium processors.Control mechanism. One of the following constants, defined in IFPORT.F90:• FILE$FIRST – First matching file found.• FILE$LAST – Previous file was the last valid file.• FILE$ERROR – No matching file found.Results:The result type is INTEGER(4). The result is the nonblank length of the file name if a match wasfound, or 0 if no matching files were found.To get information about one or more files, set the handle to FILE$FIRST and callGETFILEINFOQQ. This will return information about the first file which matches the name andreturn a handle. If the program wants more files, it should call GETFILEINFOQQ with the handle.GETFILEINFOQQ must be called with the handle until GETFILEINFOQQ sets handle toFILE$LAST, or system resources may be lost.The derived-type element variables FILE$INFO%CREATION, FILE$INFO%LASTWRITE, andFILE$INFO%LASTACCESS contain packed date and time information that indicates when thefile was created, last written to, and last accessed, respectively. To break the time and date intocomponent parts, call UNPACKTIMEQQ. FILE$INFO%LENGTH contains the length of the filein bytes. FILE$INFO%PERMIT contains a set of bit flags describing access information about thefile as follows:Bit flagFILE$ARCHIVEFILE$DIRFILE$HIDDENFILE$READONLYFILE$SYSTEMAccess information for the fileMarked as having been copied to a backup device.A subdirectory of the current directory. Each MS-DOS* directorycontains two special files, "." and "..". These are directory aliasescreated by MS-DOS for use in relative directory notation. Thefirst refers to the current directory, and the second refers to thecurrent directory’s parent directory.Hidden. It does not appear in the directory list you request fromthe command line, the Microsoft* visual developmentenvironment browser, or File Manager.Write-protected. You can read the file, but you cannot makechanges to it.Used by the operating system.2-121
