Detailed Description
Macro Definition Documentation
| #define LWIP_FIONREAD_LINUXMODE 0 |
LWIP_FIONREAD_LINUXMODE==0 (default): ioctl/FIONREAD returns the amount of pending data in the network buffer. This is the way windows does it. It's the default for lwIP since it is smaller. LWIP_FIONREAD_LINUXMODE==1: ioctl/FIONREAD returns the size of the next pending datagram in bytes. This is the way linux does it. This code is only here for compatibility.
| #define LWIP_POSIX_SOCKETS_IO_NAMES 1 |
LWIP_COMPAT_SOCKETS==1: Enable BSD-style sockets functions names through defines. LWIP_COMPAT_SOCKETS==2: Same as ==1 but correctly named functions are created. While this helps code completion, it might conflict with existing libraries. (only used if you use sockets.c) LWIP_POSIX_SOCKETS_IO_NAMES==1: Enable POSIX-style sockets functions names. Disable this option if you use a POSIX operating system that uses the same names (read, write & close). (only used if you use sockets.c)

LWIP_SOCKET_OFFSET==n: Increases the file descriptor number created by LwIP with n. This can be useful when there are multiple APIs which create file descriptors. When they all start with a different offset and you won't make them overlap you can re implement read/write/close/ioctl/fnctl to send the requested action to the right library (sharing select will need more work though).
