Adding of the appropropriate structs to the plrtoascii utility. Incoorporation of changes from old circlemud CVS snapshot this also gives more info on SYSERRors. cleanup of zmalloc language (shit->tmp) PRF_ROOMFLAGS has been renamed to PRF_SHOWVNUMS for clarity. "Deaf" has been changed to "No_shout" in preference_bits, for clarity. Addition of hindex (help index) command. who command added argument -g and -l to check who are grouped (and leaders) toggle has been expanded, and the commands nohassle, holylight, color, buildwalk, syslog and roomflags were moved to toggles. renaming of some vars in dg files (xxx -> dg_xxx) for clarity. set <player> password can now be used by other people than the first implementor - id check removed. fix of a couple of minor bugs: - crash bug related to freeing a pointer twice - ascii pfiles bug. - host was not updated correctly after switch to ascii pfiles. Todo: make "who #-#", "who #-" and "who -#" all work as "who -l #-#" did before Remove redundant commands which are now toggles. Make script variables save to pfile instead of its own file.

/* Function prototypes ************************************************/
|
|
|
|
/*
|
|
* For reasons that perplex me, the header files of many OS's do not contain
|
|
* function prototypes for the standard C library functions. This produces
|
|
* annoying warning messages (sometimes, a huge number of them) on such OS's
|
|
* when compiling with gcc's -Wall.
|
|
*
|
|
* Some versions of CircleMUD prior to 3.0 patchlevel 9 attempted to
|
|
* include prototypes taken from OS man pages for a large number of
|
|
* OS's in the header files. I now think such an approach is a bad
|
|
* idea: maintaining that list is very difficult and time-consuming,
|
|
* and when new revisions of OS's are released with new header files,
|
|
* Circle can break if the prototypes contained in Circle's .h files
|
|
* differs from the new OS header files; for example, Circle 3.0
|
|
* patchlevel 8 failed with compiler errors under Solaris 2.5 and
|
|
* Linux 1.3.xx whereas under previous revisions of those OS's it had
|
|
* been fine.
|
|
*
|
|
* Thus, to silence the compiler warnings but still maintain some level of
|
|
* portability (albiet at the expense of worse error checking in the code),
|
|
* my solution is to define a "typeless" function prototype for all problem
|
|
* functions that have not already been prototyped by the OS. --JE
|
|
*
|
|
* 20 Mar 96: My quest is not yet over. These definitions still cause
|
|
* clashes with some compilers. Therefore, we only use these prototypes
|
|
* if we're using gcc (which makes sense, since they're only here for gcc's
|
|
* -Wall option in the first place), and configure tells gcc to use
|
|
* -fno-strict-prototypes, so that these definitions don't clash with
|
|
* previous prototypes.
|
|
*
|
|
* 4 June 96: The quest continues. OSF/1 still doesn't like these
|
|
* prototypes, even with gcc and -fno-strict-prototypes. I've created
|
|
* the constant NO_LIBRARY_PROTOTYPES to allow people to turn off the
|
|
* prototyping.
|
|
*
|
|
* 27 Oct 97: This is driving me crazy but I think I've finally come
|
|
* up with the solution that will work. I've changed the configure
|
|
* script to detect which prototypes exist already; this header file
|
|
* only prototypes functions that aren't already prototyped by the
|
|
* system headers. A clash should be impossible. This should give us
|
|
* our strong type-checking back. This should be the last word on
|
|
* this issue!
