| Does the compiler supports void pointers |
 Posted: Sat Nov 20, 2004 8:08 pm |

my code is:
struct mystruct
{
void * var;
}
when I try to compile, I get an unknown type error in front of void.
What could be the problem and how can I solve this? |

See the posts I have made about this in the past.
CCS, follows the _original_ K&R 'C' definition, with a 'void' being 'nothing'. With this, you cannot have a pointer to 'nothing', so what you post won't work. Latter, in ANSI C, the definition of a 'void' was changed, so it became in some circumstances 'nothing', but in other places an 'undefined type'. This latter definition, allowed you to have a 'void pointer', which then was automatically 'cast' to the required type when used.
Replace your pointer, with a pointer to any data type (generally an int8), and then manually cast it to the required type when used.
