Yes, thats how the OS libs work. e.g. ASL lib:
*asl_fr.FileRequest=AllocASLRequest_(...)
if *asl
if AslRequest_(*asl_fr,...)
; do whatever
End If
FreeAslRequest_ *asl_fr
end if
And at the risk of starting a riot:
struct UDPvars {
int dunno;
int address;
int etc;
}
struct UDPvars *allocudp(void) /* maybe have some tags? */
{
return((struct UDPvars *)AllocMem(sizeof(struct UDPvars),
MEMF_CLEAR|MEMF_ANY));
}
void freeudp(struct UDPvars *udp)
{
if(udp) FreeMem(udp, sizeof(struct UDPvars));
}
int connectudp(struct UDPvars *udp, int address)
{
if(udp)
{
udp->address = address;
/* do whatever else here, will affect only the copy
that the program has passed to your shared lib */
}
}
