DtDtsDataTypeToAttributeValue(library call) DtDtsDataTypeToAttributeValue(library call)NAMEDtDtsDataTypeToAttributeValue -- get an attribute value for a specified data typeSYNOPSIS#include <Dt/Dts.h> char *DtDtsDataTypeToAttributeValue( const char *datatype, const char *attr_name, const char *opt_name);DESCRIPTIONThe 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 VALUEUpon successful completion, the DtDtsDataTypeToAttributeValue function returns a pointer to a data attribute value string, or NULL if no value could be determined.APPLICATION USAGEThe 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).EXAMPLESThe 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); }SEE ALSODt/Dts.h, DtDtsFileToDataType(3), DtDtsLoadDataTypes(3), DtDtsRelease(3), DtDtsFreeAttributeValue(3).
