compilation wrning in altix350:(Typecasting from int to void *)

[ramakanta.sinha]

Hi,

While typecasting an integer to (void *) the following warning
is found.

warning: cast to pointer from integer of different size.

This is the line where typecasting is done.
fld->base = (void *)(((fld->f90_table_index-1) *
F90_MAX_FLD_SIZE_IN_BYT
ES + 1 ));

fld->base is of type (void *)
((fld->f90_table_index-1) * F90_MAX_FLD_SIZE_IN_BYTES + 1 ) is an
integer.

This is a c++ code, compiled using c++ compiler in altix350.


Waiting for immediate help to resolve the warning.

Thanks in advance,
Rama Kanta Sinha.

Why do you cast an integer to a pointer?

Well, don't cast an integer to a pointer or use an integer type that has the
same size as a pointer on your architecture. Your compiler's manual should
tell you the sizes.
