NAME

closefrom — delete many descriptors

SYNOPSIS

#include <unistd.h>

int
closefrom(int fd);

DESCRIPTION

The closefrom() call deletes all descriptors numbered fd and higher from the per-process file descriptor table. 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.
