PM54284: NEGATIVE ONE BYTE SIGNED BINARY INTEGER IS MAPPED INCORRECTLY TO AN UNSIGNED CHARACTER INTEGER ON UNIX OR ZLINUX PLATFORM

APAR status

• Closed as program error.

Error description

• A negative one byte Signed Binary Integer is mapped incorrectly
  as if it is an Unsigned Binary Integer when mapped to an
  Unsigned Character Integer on the Unix or zLinux platform.

  Circumvention: None
  

Problem summary

• Users Affected:
  WebSphere Transformation Extender customers who use 1-byte
  binary integers on Unix.
  
  Problem Description:
  Signed binary integer mapped as unsigned on Unix.
  
  Platforms Affected:
   1    AIX (32BITS)
    2    AIX (64BITS)
    3    DataPower32
    4    HPUX(Itanium) (32 BITS)
    5    HPUX(Itanium) (64 BITS)
    6    HPUX(risc) (32BITS)
    7    HPUX(risc) (64BITS)
    8    LINUX (32 BITS)
    9    LINUX (64 BITS)
    10    Solaris (32BITS)
    11    Solaris (64BITS)
    12    z/USS (32 BITS)
    13    zLinux (64 BITS)
  

Problem conclusion

• By default, a type defined as "char" is unsigned on Unix (it's
  signed on Windows).  So I have to specifically cast it to
  "(signed char *)" to get the sign to take effect.
