Problem summary

  PRODUCT:  z/TPF
  FUNCTIONAL AREA:  'C' LANGUAGE SUPPORT
  SHIPPED IN PUT:  10
  
  ABSTRACT:
  A CTL-230 may occur when logging system messages using syslog.
  
  PACKAGE CONTENTS:
  Source Segments:
  (C) base/rt/csylgd.c
  
  Object Only Binaries:
  None.
  
  Configuration Independent Binaries:
  (C) base/obj/csylgd.o
  (C) base/load/CSYL.so
  
  Support Files:
  base/lst/csylgd.lst
  base/lst/CSYL.map
  
  OTHER BINARIES TO BUILD: NO
  None.
  
  COMMENTS:
  When logging messages, function fprintlog() in program segment
  csylgd.c declares and initializes an integer sized variable,
  bss, to indicate that it is not operating in the BSS and that a
  cebic_restore() must be issued before exiting. When logging
  messages to file, fprintlog() will check the BSS indicator in
  the ECB. If it is not operating in the BSS, a cebic_save() and
  cebic_goto_bss() are issued. Otherwise, the variable, bss, is
  set to indicate that it is operating in the BSS. However, there
  are other paths in this function where the BSS indicator in the
  ECB is not checked. Yet, before exiting, variable bss is still
  checked to determine if a cebic_restore() needs to be issued.
  If, for example, fprintlog() is writing to tape, then a
  cebic_restore() is needlessly issued and a CTL-230 will occur.
  

Problem conclusion

• SOLUTION:
  In program segment csylgd.c, function fprintlog() has been
  updated to always check the BSS inidicator in the ECB, set
  variable bss, and issue cebic_save and cebic_restore
  accordingly. Before exiting, variable bss will correctly
  indicate whether or not a cebic_restore() must be issued. In
  addition, segment csylgd.c was updated to call ascii2ebcdic()
  and convert a message only if the prior call to recvfrom()
  returned a valid message.
