Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

  Variable:  _fileinfo
 
  Include:   <stdlib.h>
 
  Syntax:    int _fileinfo;
 
     The _fileinfo variable determines whether or not a process's open
     file information, in the form of the _C_FILE_INFO entry in the
     environment, will be passed to child processes. If _fileinfo is 0,
     the _C_FILE_INFO information is not passed to the child processes.
     If _fileinfo is not 0, the _C_FILE_INFO information is passed to
     child processes.
 
     By default, _fileinfo is 0 and thus the _C_FILE_INFO information
     is not passed to child processes. There are two ways to modify
     the default value of _fileinfo:
 
        ■ Link the supplied object file FILEINFO.OBJ into your program.
          Use the /NOE option to avoid multiple symbol definitions.
 
        ■ Set the _fileinfo variable to a nonzero value directly
          within your C program.
