# NAME

closefrom — delete many descriptors

# SYNOPSIS

#include <unistd.h>

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.

# SEE ALSO
