- * Public domain dup2() lookalike
- * by Curtis Jackson @ AT&T Technologies, Burlington, NC
- * electronic address:  burl!rcj
- *
- * dup2 performs the following functions:
- *
- * Check to make sure that fd1 is a valid open file descriptor.
- * Check to see if fd2 is already open; if so, close it.
- * Duplicate fd1 onto fd2; checking to make sure fd2 is a valid fd.
- * Return fd2 if all went well; return BADEXIT otherwise.
