Coding

The following is a BASIC Sockets library: 

 REM > BLib.Socket
 DEFFNSocket_Open(   X%!4, X%!8, X%!12):A%=0
 DEFFNSocket_Bind(   X%!4, X%!8, X%!12):A%=1
 DEFFNSocket_Listen( X%!4, X%!8)       :A%=2
 DEFFNSocket_Accept( X%!4, X%!8, X%!12):A%=3
 DEFFNSocket_Connect(X%!4, X%!8, X%!12):A%=4
 DEFFNSocket_Read(   X%!4, X%!8, X%!12):A%=5
 DEFFNSocket_Write(  X%!4, X%!8, X%!12):A%=8
 DEFFNSocket_Close(  X%!4)             :A%=16
 !X%=&814:X%?2=A%:A%=192:CALL &FFF1:IFX%?3:=-X%?3 ELSE =X%!4

The calls return a negative number if the call fails, or a positive number (or zero) if the call succeeds, being the returned socket number or byte count, etc.

Specification

 On entry:
     XY?0  = send block length
     XY?1  = receive block length
     XY?2  = command, 0-63=Socket, 64-127=Resolver, 128-255=Reserved
     XY?3  = 0, returns 0 or error value
     XY!4  => host name
 
 On exit:
     XY?2 = 0 if call supported, unchanged if call unsupported or no handler present
     XY?3 = 0 or returned error
     XY!4 onwards: any returned data

Resolver Commands

Commands passed in XY?2 are those in the RISC OS Resolver_ SWIs plus &40, that is: 

 &40 Resolver_GetHostByName
     On entry:  X%!4=>name,
     On exit:   X%!4=>name, X%!8=>aliases, X%!12=>type, X%!16=length, X%!20=>IP addresses
 &41 Resolver_GetHost
     On entry:  X%!4=>name,
     On exit:   X%!4=>name, X%!8=>aliases, X%!12=>type, X%!16=length, X%!20=>IP addresses

Coding

The following is a BASIC Resolver library: 

 REM > BLib.DNS
 DEFFNDNS_GetHost(A$):A%=65
 DEFFNDNS_GetHostByName(A$):A%=64
 !X%=&1808:X%?2=A%:X%!4=name%:$name%=A$:A%=192:CALL&FFF1:=X%+4 AND X%?3=0

The calls return zero if the call fails, or the address of an inet address structure.
