Hello.

I'm writting an iopkt driver based on speedo model.
I'm porting a code from io-net.

io-pkt drivers expects malloc and free with more than 1 arg such as :
free(freeptr, M_TEMP);
malloc(strlen(optstring) + 1, M_TEMP, M_NOWAIT);

wereas doc is saying :
Synopsis:

#include <stdlib.h>

void* malloc( size_t size );

Arguments:

size
    The number of bytes to allocate.

Where does this macro are defined ?
Is it possible to do not use them ?

Thanks.
Guillaume
