- [Module coders] Added new function: do_cmd(cptr, sptr, cmd, parc, parv) which is an
  uniform method to call any other commands. For more info, see description in src/packet.c.
  This will be used for any further modulization of commands that need to call other
  commands, like NICK (will be done soon).

Code: Select all

/** Calls the specified command.
 * PURPOSE:
 *  This function is especially meant for calling modulized commands,
 *  both from the core and from (eg:) module A to a command in module B.
 *  An alternative to this is MOD_Dep, but this requires a lot more
 *  effort, is more error phrone and is not a general solution
 *  (but it is slightly faster).
 * PARAMETERS:
 *  Parameters are clear.. the usual cptr, sptr, parc, parv stuff.
 *  'cmd' is the command string, eg: "JOIN"
 * RETURN VALUE:
 *  The value returned by the command function, or -99 if command not found.
 * IMPORTANT NOTES:
 *  - make sure you terminate the last parv[] parameter with NULL,
 *    this can easily be forgotten, but certain functions depend on it,
 *    you risk crashes otherwise.
 *  - be sure to check for FLUSH_BUFFER (-5) return value, especially
 *    if you are calling functions that might cause an immediate kill
 *    (eg: due to spamfilter).
 *  - obvious, but... do not stuff in insane parameters, like a parameter
 *    of 1024 bytes, most of the ircd code depends on the max size of the
 *    total command being less than 512 bytes. Same for parc < MAXPARA.
