DtDtsDataTypeToAttributeValue(libraDtDtsDataTypeToAttributeValue(library call)

NAME
       DtDtsDataTypeToAttributeValue  — get an attribute value for a specified
       data type

SYNOPSIS
       #include <Dt/Dts.h>
       char *DtDtsDataTypeToAttributeValue(
       const char *datatype,
       const char *attr_name,
       const char *opt_name);

DESCRIPTION
       The DtDtsDataTypeToAttributeValue returns an attribute  value  for  the
       specified data type name.

       The datatype argument is a pointer to a data type name string.

       The attr_name argument is a name of the attribute.

       The  opt_name  argument	can be used to specify a name to be associated
       with the data type.  If the opt_name argument is not NULL, it  is  used
       as  a  pseudo file name in typing; otherwise, certain attributes may be
       returned as NULL because the filename components could  not  be	deter‐
       mined.

RETURN VALUE
       Upon  successful completion, the DtDtsDataTypeToAttributeValue function
       returns a pointer to a data attribute value string, or NULL if no value
       could be determined.

APPLICATION USAGE
       The  application	 should use the DtDtsFreeAttributeValue(3) function to
       release the memory for the returned value.

       The opt_name argument is useful when the attribute being returned  con‐
       tains  a	 modifier  string that depends on having a file name included.
       For example, if the INSTANCE_ICON attribute had the value  %name%.icon,
       opt_name	 would	be  used to derive the %name% portion of the attribute
       value.  See dtdtsfile(4).

EXAMPLES
       The following takes a list of files as  arguments  and  determines  the
       description and actions for each file:

       #include <Dt/Dts.h>
       #define ATTRIBUTE1      "DESCRIPTION"
       #define ATTRIBUTE2      "ACTIONS"
       main (int argc, char **argv)
       {
	       char    *attribute;
	       char    *datatype;
	       /* load data types database */
	       DtDtsLoadDataTypes();
	       argv++;
	       while (*argv) {
		       /* get data type file file */
		       datatype = DtDtsFileToDataType(*argv);
		       /* get first attribute for datatype */
		       attribute = DtDtsDataTypeToAttributeValue(datatype,
					       ATTRIBUTE1, *argv);
		       if (attribute)
			       printf("%s for file %s is %s\n",
				       ATTRIBUTE1, *argv, attribute);
		       /* get second attribute for datatype */
		       attribute = DtDtsDataTypeToAttributeValue(datatype,
					       ATTRIBUTE2, NULL);
		       if (attribute)
			       printf("%s for file %s is %s\n",
				       ATTRIBUTE2, *argv, attribute);
		       argv++;
	       }
	       DtDtsRelease();
	       exit(0);
       }
