SOCKBINWRITE Statement

SOCKBINWRITE(integer-socket, integer-buffer, integer-length)

Writes binary data from memory to a connected socket.

• integer-socket — socket file descriptor (e.g. from CONNECT or SOCKACCEPT).
• integer-buffer — memory handle/pointer returned by MEMALLOC.
• integer-length — number of bytes to write.

---

Examples

size = FILESIZE(file$)
buf  = MEMALLOC(size)
BINREAD fh, buf, size
 
SOCKWRITE client, "Content-Length: "; size; CHR$(13); CHR$(10); CHR$(13); CHR$(10);
SOCKBINWRITE client, buf, size
SOCKFLUSH client
 
MEMRELEASE buf

Notes

• Intended for sending file contents or other raw buffers.
• Socket must be connected; use SOCKSTATUS to check.
• May write less than requested if the peer closes; handle errors accordingly.
