Embedded TCP/IP stack: fnet_error_get

Returns the last error that occurred.

Returns

This function returns the error code for the last socket operation that failed.
The error codes are defined by the fnet_error_t.

fnet_error_set()

When a particular socket function indicates that an error has occurred, this function should be called to retrieve the appropriate error code.
A successful socket function call, or a call to fnet_error_get(), does not reset the error code. To reset the error code, use the fnet_error_set() function call with error set to zero (FNET_ERR_OK).
