EOVERFLOWA value is too large to be stored in the target data type.
A file size, offset, or other value exceeds the maximum representable value of the data type. This commonly occurs with 32-bit programs accessing files larger than 2 GB.
Compile with large file support by defining _FILE_OFFSET_BITS=64. Use 64-bit data types for file offsets and sizes.
ENOTSOCKA socket operation was attempted on a file descriptor that is not a socket.
SIGUSR1 (10)A user-defined signal for application-specific purposes. The default action is to terminate.
