>>ITEM: N01015

>>DATE: 11/14/97

>>TYPE: Bug

>>TITLE: Parameter passing bug in N_D_CAPGET/SET and N_D_PJGET

>>PRODUCT(S): NetLib for FoxPro DOS, only

>>PLATFORM(S):
NetWare 4.x with Client32, VLM or Micosoft Service for NDS

>>SUMMARY:
N_D_CAPGET, N_D_CAPSET and N_D_PJGET sometimes fail when passing attribute numbers via arrays.

>>MORE INFORMATION:
Problem is illustrated by the following example:

DECLARE aAttr[1], aValue[1] aAttr[1] = CAP_QUEUE =N_D_CAPGET(1,@aAttr,@aValue)

Afterwards aValue[1] may remain unchanged as if the parameter number were ignored.

>>RESOLUTION/FIX:
There are two possible work-arounds:

 

1. Use In-line parameters, e.g.,

   cQueue = "" =N_D_CAPGET(1,CAP_QUEUE,@cQueue)

    

2. Use string parameter names, e.g.,

   DECLARE aAttr[1], aValue[1] aAttr[1] = "Queue" =N_D_CAPGET(1,@aAttr,@aValue)

   If you like the convenience of using #defines, you can redefine the various CAP_* defines to use strings instead of parameters, e.g.,

   #define CAP_STATUS "STATUS" #define CAP_COMMAND "COMMAND" #define CAP_AUTOEND "AUTOEND" #define CAP_BANNER "BANNER" #define CAP_COPIES "COPIES" #define CAP_CPL "CLP" #define CAP_FORMNO "FORMNO" #define CAP_LPP "LPP" #define CAP_NOFF "NOFF" #define CAP_NOTIFY "NOTIFY" #define CAP_QUEUE "QUEUE" #define CAP_SERVER "SERVER" #define CAP_TABS "TABS" #define CAP_TIMEOUT "TIMEOUT" #define CAP_USER "USER" #define CAP_JOBNO "JOBNO" #define CAP_RESET "RESET" #define CAP_RESETMAX "RESETMAX" #define CAP_SETUP "SETUP" #define CAP_SETUPMAX "SETUPMAX" #define CAP_DESCRIPTION "DESCRIPTION" #define CAP_FNAME "FNAME"
