Summary:
The Microsoft run-time library functions fopen() and open() do not
screen for invalid filenames. These functions accept a filename string
with an embedded space. For example, the following program creates the
file "he llo.dat" (without the quotation marks).
This error is not the result of a problem with fopen() or open(). The
functions fopen() and open() should not be expected to screen
filenames. This activity should be handled by the program using these
routines. Filename screening is not specified in the "Microsoft C
Optimizing Compiler: Run-Time Library Reference" manual; this applies
to both MS-DOS and OS/2.
However, the creation of this file may cause some difficulties under
MS-DOS. The simplest way to delete such a file is "del *.dat" (without
the quotation marks).
Sample Code
-----------
#include <stdio.h>
FILE *fh;
void main(void)
{
fh = fopen ("he llo.dat", "w+");
fclose(fh);
}
