/SYMBOLS 

/SYMBOLS

This option displays the COFF symbol table. Symbol tables exist in all object files. A COFF symbol table appears in an image file only if it is linked with /DEBUG.

The following is a description of the output for /SYMBOLS. Additional information on the meaning of /SYMBOLS output can be found by looking in winnt.h (IMAGE_SYMBOL and IMAGE_AUX_SYMBOL), or COFF documentation.

Given the following sample dump:

Dump of file main.obj
File Type: COFF OBJECT

Summary

      26 .drectve
      23 .text

Remarks

The following description, for lines that begin with a symbol number, describes columns that have information relevant to users:

  • The first three-digit number is the symbol index/number.

  • If the third column contains SECTx, the symbol is defined in that section of the object file. But if UNDEF appears, it is not defined in that object and must be resolved elsewhere.

  • The fifth column (Static, External) tells whether the symbol is visible only within that object, or whether it is public (visible externally). A Static symbol, _sym, wouldn't be linked to a Public symbol _sym; these would be two different instances of functions named _sym.

The last column in a numbered line is the symbol name, both decorated and undecorated.

Only the /HEADERS DUMPBIN option is available for use on files produced with the /GL compiler option.
