Specifications

Not all file systems/devices recognize this option.
mode specifies the permissions to use, if a new file is created. It is unused by current file systems, but is
maintained for compatibility.
Calls to open() are thread-safe only if the implementation of open() provided by the driver that is
manipulated is thread-safe.
Return
The return value is the new file descriptor, and –1 otherwise. If an error occurs, errno is set to indicate the
cause.
