NAME
DtDtsSetDataType - set the data type of a directory
SYNOPSIS
#include <Dt/Dts.h>
char *DtDtsSetDataType(const char *dirpath,
const char *datatype,
const int override);
DESCRIPTION
The DtDtsSetDataType() function sets the data type of a
directory. This may be accomplished by adding a file named
with a leading dot to the directory.
The dirpath argument is a pathname of the directory.
The datatype argument is a data type.
If the value is already set, DtDtsSetDataType() does not
change the value unless the override argument is set to
True.
RETURN VALUE
Upon successful completion, the DtDtsSetDataType() function
returns a pointer to a data type string, or NULL if it was
unable to set or retrieve the data type.
APPLICATION USAGE
Directories can have data types associated with them, just
as regular files can. For example, a file manager may
choose to alter the appearance of the directory's icon based
on this data type or a system may use a directory of files
as an means of supporting a complex form of data, such as a
compund document.
