You need to do following setting for building the ThreadX and NetX Duo components of a BSD application.

ThreadX

The ThreadX library must define bsd_errno in the thread local storage. We recommend the following procedure:

1. In tx_port.h, set one of the TX_THREAD_EXTENSION macros as follows:

   #define TX_THREAD_EXTENSION_3       int bsd_errno                       

2. Rebuild the ThreadX library.

Note that if TX_THREAD_EXTENSION_3 is already used, the user is free to use one of the other TX_THREAD_EXTENSION macros.

NetX Duo

Before using NetX Duo BSD Services, the NetX Duo library must be built with NX_ENABLE_EXTENDED_NOTIFY_SUPPORT defined. By default it is not defined. If the BSD raw sockets are to be used, the NetX Duo library must be built with NX_ENABLE_IP_RAW_PACKET_FILTER defined.

Hi @bo-ms

I did add a int bsd_errno in tx_api.h Also, my question why can't we name it as tx_errno in tx_api.h, and in the nx_bsd.c and nxd_bsd.c we can have a bsd_errno while setting it ie.

VOID set_errno(INT bsd_errno)
{
...
current_thread_ptr -> tx_errno = bsd_errno; 
...
}

Just a suggestion,

@ameya7295 why do you suggest the name tx_errno rather than bsd_errno?

[ameya7295]

@goldscott Yes,I am suggesting the same because, if in future we want to use this variable in some other way then we will have to set the bsd_errno which is in tx_api.h . Which will be quite confusing to understand which errno to set. As ThreadX follows the noun verb naming convection user will will be searching for tx_errno. What is your take on this ?

[goldscott]

Hi @ameya7295 - we're going to continue using bsd_errno in the TX_THREAD struct. The member bsd_errno is only needed when using our BSD layer.

You should add ; at the final of define. #define TX_THREAD_EXTENSION_3 int bsd_errno;
