NAME

       DtDtsFileToAttributeValue -- get a specified attribute value for a file

SYNOPSIS

       #include <Dt/Dts.h>
       char *DtDtsFileToAttributeValue(
       const char *filepath,
       const char *attr_name);

DESCRIPTION

       The DtDtsFileToAttributeValue function returns a data attribute value for the specified file.

       The filepath argument is the pathname of the file.

       The attr_name argument is a pointer to an attribute name string.

RETURN VALUE

       Upon  successful completion, the DtDtsFileToAttributeValue 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.

EXAMPLES

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

       #include <Dt/Dts.h>
       #define ATTRIBUTE       "DESCRIPTION"
       main (int argc, char **argv)
       {
	       char    *attribute;
	       /* load data types database */
	       DtDtsLoadDataTypes();
	       argv++;
	       while (*argv) {
		       /* get attribute for file */
		       attribute = DtDtsFileToAttributeValue(*argv, ATTRIBUTE);
		       if (attribute)
			       printf("%s: %s
", *argv, attribute);
		       argv++;
	       }
	       DtDtsRelease();
	       exit(0);
       }

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 contains 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
",
				       ATTRIBUTE1, *argv, attribute);
		       /* get second attribute for datatype */
		       attribute = DtDtsDataTypeToAttributeValue(datatype,
					       ATTRIBUTE2, NULL);
		       if (attribute)
			       printf("%s for file %s is %s
",
				       ATTRIBUTE2, *argv, attribute);
		       argv++;
	       }
	       DtDtsRelease();
	       exit(0);
       }
