CLOSEFROM(2) System Calls Manual CLOSEFROM(2)

closefromdelete many descriptors

#include <unistd.h>

closefrom(int fd);

The () 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 the global integer variable errno is set to indicate the error.

closefrom() will fail if:

fd is greater than all open file descriptors.
An interrupt was received.
