closefrom —

delete many descriptors

RETURN VALUES

Upon successful completion, the value 0 is returned; otherwise the value -1 is returned and the global variable errno is set to indicate the error.

ERRORS

closefrom() will fail if:

[EBADF]

fd is greater than all open file descriptors.

[EINTR]

An interrupt was received.

SEE ALSO

close(2)

STANDARDS

closefrom() is a BSD and Solaris extension.

HISTORY
