WSAEFAULT 10014, Why setsockopt returning -1?
The WSAEFAULT
error with error code 10014 means that the buffer passed to a system call is too small for the operation to complete. Specifically, in the case of setsockopt
, it indicates that the optval
or optlen
parameter is not a valid part of the user address space. This can occur if the size of the buffer is too small, or if the buffer is not properly aligned.
To resolve this error, you should ensure that the optval
and optlen
parameters are properly set and aligned. You may need to allocate a larger buffer or adjust the alignment of the buffer.
Here are some common causes and solutions for this error:
- The size of the buffer passed to
setsockopt
is not large enough to hold the requested information. Try increasing the size of the buffer and see if the error goes away. - The
optval
oroptlen
parameter is not properly aligned. You may need to adjust the alignment of the buffer to ensure that it is properly aligned. - The
optval
parameter is pointing to an invalid address. Check to make sure that theoptval
parameter is properly initialized and that it points to a valid memory address. - The
optlen
parameter is not set correctly. Make sure that theoptlen
parameter is set to the correct size of the buffer.
If you have tried these solutions and are still experiencing issues, you may want to consult the documentation or seek help from the community or support team for the specific function or library you are using.
