// +build darwin
package syscall
// This file defines errno and constants to match the darwin libsystem ABI.
// Values have been copied from src/syscall/zerrors_darwin_amd64.go.
// This function returns the error location in the darwin ABI.
// Discovered by compiling the following code using Clang:
//
// #include <errno.h>
// int getErrno() {
// return errno;
// }
//
//export __error
func libc___error() *int32
// getErrno returns the current C errno. It may not have been caused by the last
// call, so it should only be relied upon when the last call indicates an error
// (for example, by returning -1).
