Zig 0.17.0-dev (Split by item)

This is an example of documentation generated by ZigDoc, an alternative to Zig's built-in Auto Doc feature. See also examples in other modes/formats. The project being documented here (as the example) is the Zig library itself.

errno

Obtains errno from the return value of a system function call.

For some systems this will obtain the value directly from the syscall return value; for others it will use a thread-local errno variable. Therefore, this function only returns a well-defined value when it is called directly after the system function call whose errno value is intended to be observed.
