Use getpassphrase() instead of getpass() if available. 2000-05-20 02:41:26 +08:00			`#if defined(HAVE_GETPASSPHRASE)`
Round one of LDAP_F() macro changes. In this round we rename macros into our namespace and limit use to headers. A subsequent round will add macros to separately handle forward declarations of variables from declaration of function prototypes. The last round will add additional macros for declaring actual variables and functions. 2000-06-19 03:48:07 +08:00			`LDAP_LIBC_F(char*)(getpassphrase)();`

Remove extern declarations of library functions from source.c. This could cause problems on odd systems. The generic headers should be extended as needed to include necessary system headers or, if necessary, make explicit declarations. Extended ac/string.h header to look for string.h/strings.h if STDC_HEADERS is not defined. Also provide basic declarations for str*() functions. This could cause problems on odd systems. Extended ac/unistd.h header to define basic declaration for misc functions that might be missing from headers. This includes externs for getenv(), getopt(), mktemp(), tempname(). Protect fax500.h from multiple inclusion. Moved includes of system/generic headers back to source files. Made mail500 helper functions static. Fixed includes of ctype.h, signal.h, etc. to use generics. lutil/tempname.c: was including stdlib.h twice, one should stdio.h. Wrapped <sys/resource.h> with HAVE_SYS_RESOURCE_H. lber/io.c/ber_get_next(): Changed noctets back to signed. Used with BerRead which expects signed int as second arg and returns signed int. 1998-11-16 13:07:27 +08:00			`# include <getopt.h>`

Back out K&Rification change; would only be needed in ldap.h and lber.h. 1998-11-17 12:07:31 +08:00			`#elif !defined(HAVE_GETOPT)`

Update lutil_lockf (aka: ldap_lockf) to hide implementation in library, not header. Eliminate need for <ac/unistd.h> to sometimes include <fcntl.h> and/or <sys/file.h>. Change lock API to expect fd not FILE*. Allows wider use and eliminates requirement that lutil_lockf.h depencency on stdio.h. Implemented lockf, fcntl, and flock locking in lutil/lockf.c. Additional implementations (including no-op) may be needed. Update slapd/lock.c and slurpd/lock.c to use new API. 1999-03-29 05:39:02 +08:00			`/* use lutil file locking */`
