Description

The tdump.exe program displays useful information about binary files, especially .exe, .dll, .bpl, .obj, and .lib files. The first file named on the command line is the input file to examine. (You cannot use wildcards to specify more than one file.) The second filename is the output filename. If you do not supply a listfile, tdump writes to the standard output. The output from tdump is usually voluminous, so a listfile is usually a good idea. Options and filenames can be mixed in any order.

Unlike switches for the other command-line tools, switches for tdump are case sensitive. You can start a switch with a hyphen (-) or slash (/). Unlike when using the compiler, you cannot concatenate switches, even if you use a slash.

Object files can be in COFF (Common Object File Format) or OMF (Intel’s Object Module Format). COFF is used by Visual C++ and other compilers, but not by any Borland product. OMF is used by Delphi, Borland C++, and other compilers. If you use the wrong options with the wrong file, tdump prints an error message and exits.
