/* NAME
/* unix_pass_fd_fix 3
/* SUMMARY
/* file descriptor passing bug workarounds
/* SYNOPSIS
/* #include <iostuff.h>
/*
/* void set_unix_pass_fd_fix(workarounds)
/* const char *workarounds;
/* DESCRIPTION
/* This module supports programmatic control over workarounds
/* for sending or receiving file descriptors over UNIX-domain
/* sockets.
/*
/* set_unix_pass_fd_fix() takes a list of workarounds in external
/* form, and stores their internal representation. The result
/* is used by unix_send_fd() and unix_recv_fd().
/*
/* Arguments:
/* .IP workarounds
/* List of zero or more of the following, separated by comma
/* or whitespace.
/* .RS
/* .IP cmsg_len
/* Send the CMSG_LEN of the file descriptor, instead of
/* the total message buffer length.
/* .RE
/* SEE ALSO
/* unix_send_fd(3) send file descriptor
/* unix_recv_fd(3) receive file descriptor
/* DIAGNOSTICS
/* Fatal errors: non-existent workaround.
/* LICENSE
/* .ad
/* .fi
/* The Secure Mailer license must be distributed with this software.
