MPE_CaptureFile
Sets the base filename used to capture output from updates 
Synopsis
#include "mpe.h" 
int MPE_CaptureFile( handle, fname, freq )
MPE_XGraph handle;
char       *fname;
int        freq;
Input Parameters
- handle 
- MPE graphics handle
- fname  
- base file name (see below)
- freq   
- Frequency of updates
Return Values
- MPE_ERR_LOW_MEM 
- malloc for copy of the filename (fname) failed
- MPE_ERR_BAD_ARGS 
- 'handle' parameter is bad
- MPE_SUCCESS 
- success
Notes
The output is written in xwd format to 'fname%d', where '%d' is the number
of the file (starting from zero).
Notes For Fortran Interface 
The Fortran interface to this routine is different from its C
counterpart and it has an additional argument, ierr, at the end
of the argument list, i.e. the returned function value (the error
code) in C interface is returned as the additional argument in
Fortran interface.  The Fortran interface is invoked with the
CALL statement.
All MPI and MPE objects, MPI_Comm, MPE_XGraph and MPE_Color, are
of type INTEGER in Fortran.
Additional Notes for Fortran Interface 
The trailing blanks in Fortran 'CHARACTER' string argument will be
ignored.
