"The idea behind B<fexecve>() is to allow the caller to verify (checksum) "

"suffice, since, between the two steps, the filename, or a directory prefix "
"of the pathname, could have been exchanged (by, for example, modifying the "
"target of a symbolic link). B<fexecve>() does not mitigate the problem "
"that the I<contents> of a file could be changed between the checksumming and "

"The natural idiom when using B<fexecve>() is to set the close-on-exec flag "
"on I<fd>, so that the file descriptor does not leak through to the program "
"that is executed. This approach is natural for two reasons. First, it "
"prevents file descriptors being consumed unnecessarily. (The executed "
"program normally has no need of a file descriptor that refers to the program "
"itself.) Second, if B<fexecve>() is used recursively, employing the close-"
"on-exec flag prevents the file descriptor exhaustion that would result from "
"the fact that each step in the recursion would cause one more file "
"descriptor to be passed to the new program. (But see BUGS.)"
