VistaIODecodeAttrValue(3)


NAME

   VistaIODecodeAttrValue - decode an attribute value

SYNOPSIS

   VistaIOBoolean VistaIODecodeAttrValue (str, dict, repn, value)
          VistaIOStringConst str;
          VistaIODictEntry *dict;
          VistaIORepnKind repn;
          VistaIOPointer value;

ARGUMENTS

   str       Specifies the attribute value to be decoded.

   dict      May  specify a dictionary to be used in recognizing the value
             supplied as a keyword, or it may be NULL

   repn      Specifies the representation in which  the  value  is  to  be
             returned. It must be one of VistaIOBitRepn, VistaIOUByteRepn,
             VistaIOSByteRepn,     VistaIOShortRepn,      VistaIOLongRepn,
             VistaIOFloatRepn,  VistaIODoubleRepn,  VistaIOBooleanRepn, or
             VistaIOStringRepn.

   value     Specifies a location at which the value is be returned.

DESCRIPTION

   VistaIODecodeAttrValue decodes the string str, returning its  value  in
   the form specified by repn.

   If  a  dictionary,  dict,  has  been  provided,  the routine determines
   whether str is a keyword defined in the dictionary. If so, it uses  the
   value associated with that keyword rather than the attribute's original
   value. (See the VistaIOdictionary(3) manual page.)

   The value obtained directly from str, or indirectly via the dictionary,
   is converted to the representation repn and then stored at the location
   pointed to by value.

RETURN VALUES

   VistaIODecodeAttrValue returns TRUE if successful and FALSE  otherwise.
   It will fail if repn is invalid, or if the str cannot be interpreted as
   a value of the type indicated by repn.

SEE ALSO

   VistaIOEncodeAttrValue(3), VistaIOGetAttr(3), VistaIOattribute(3),

NOTES

   The value argument must point to sufficient storage to contain a  value
   of the representation requested. Neither VistaIODecodeAttrValue nor the
   C compiler can automatically check that this is so.

DIAGNOSTICS

   ``Can't decode to repn.''
          The   repn   argument   is   not    one    of    VistaIOBitRepn,
          VistaIOUByteRepn, ..., VistaIOBooleanRepn, or VistaIOStringRepn.
