Targets: MS-DOS, OS/2, Win32
Dos Unit
Splits a file name into its three components.
Declaration:
procedure FSplit(Path: PathStr;
var Dir: DirStr;
var Name: NameStr;
var Ext: ExtStr);
Remarks:
Use this procedure to break down a file specification into three parts:
path, file name, and file extension. Path is of type PathStr
which is defined in the Dos unit. Dir returns the path or directory
part of Path. Name returns the actual file name without
extension. Ext returns the file extension preceded by a period (.).
It is possible that one or more of the components be returned empty.
This occurs if Path contains no such component.
For instance, if there is no path, Dir is empty.
Example:
uses
Dos;
var
Fi : File;
Direc : DirStr;
Fname : NameStr;
Exten : ExtStr;
begin
FSplit(ParamStr(1), Direc, Fname, Exten);
if Fname = '' then Halt(1);
Assign(Fi, ParamStr(1));
Erase(Fi);
end.
