This function closes all descriptors execpt stdin, stdout, and stderr, and makes sure those three are open.  Use this function when spawning a new process to ensure it isn't exec'd with any stray descriptors open.

Amanda supplies a few wrapper functions around the ordinary descriptor operations to handle a few common cases. In most cases, these functions are preferred over calling the wrapped function directly.

robust_open

in common-src/file.c

This function wraps open to retry on certain failures.

robust_close

in common-src/file.c

This function wraps close to retry on certain failures.
