cnfExprtap
- Export a C array of pointers to char, to a FORTRAN CHARACTER array
</H2>
<DL>
<DT><STRONG>Description:</STRONG>
<DD><DL>
<DD>Export a C array of pointers to char to a FORTRAN CHARACTER array.
A null character is assumed to terminate each C string - it
will not be copied.
If the C string is shorter than the space allocated to the FORTRAN
string, then pad it with blanks.
No more than `dest_len' characters will be copied for each string.
</DL>
<BR>
<DT><STRONG>Invocation:</STRONG>
<DD><DL>
<DD><TT> cnfExprtap( source_c, dest_f, dest_len, ndims, dims )
</TT>
</DL>
<BR>
<DT><STRONG>Arguments:</STRONG>
<DD>
<BR>
<DL>
<DT><STRONG>
char *const *source_c (Given)
</STRONG>
<DD>
A pointer to the input C array of pointers to char
<DT><STRONG>
char *dest_f
</STRONG>
<DD>
A pointer to the output FORTRAN array
<DT><STRONG>
int dest_len (Given)
</STRONG>
<DD>
The declared maximum number of characters in a element of the FORTRAN
array
<DT><STRONG>
int ndims (Given)
</STRONG>
<DD>
The number of dimensions of the arrays
<DT><STRONG>
const int *dims (Given)
</STRONG>
<DD>
A pointer to a 1-D array specifying the dimensions of the arrays.
</DL>
<BR>
<DT><STRONG>Notes:</STRONG>
<DD>The array of pointers to char is assumed to point to null-terminated
strings. The dimensions of the array of pointers and the FORTRAN
character array must be the same.
<P>
Strictly, the input array should be declared as
`<TT>const char *const *source_c</TT>', but this would not allow
non-constant char to be given.
</DL>
