CLOSEFROM(3) |
closefrom —
delete many descriptors
#include <unistd.h>
int
closefrom(int
fd);
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.
Upon successful completion, a value of 0 is returned. Otherwise, a value of -1
is returned and errno is set to indicate the error.
closefrom() will fail if:
- [
EBADF]
- fd is invalid.
- [
EINTR]
- An interrupt was received.
This function first appeared in NetBSD 3.
