It is effectively the same as calling close(2) on each descriptor. RETURN VALUES Upon successful completion, a value of 0 is returned. Otherwise, a value of -1 is returned and errno is set to indicate the error. ERRORS closefrom() will fail if: [EBADF] fd is invalid. [EINTR] An interrupt was received.
