@ -7,7 +7,7 @@ recvfd - receive a file descriptor from a local socket peer
```**c++
#include <sys/socket.h>
int recvfd(int sockfd);
int recvfd(int sockfd, int options);
```
## Description
@ -16,6 +16,10 @@ Receive an open file descriptor from a local socket peer connected via `sockfd`.
File descriptors are sent out-of-band and do not affect the regular data streams.
The *options* argument accepts a bitmask of the following flags:
* `O_CLOEXEC`: The opened fd shall be closed on [`exec`(2)](../man2/exec.md).
## Return value
If a file descriptor is successfully received, it is returned as a non-negative integer. Otherwise, -1 is returned and `errno` is set to indicate the error.
