NAME
DtDtsBufferToDataType - get the data type for a byte stream
SYNOPSIS
#include <Dt/Dts.h>
char *DtDtsBufferToDataType(const void *buffer,
const int size,
const char *opt_name);
DESCRIPTION
The DtDtsBufferToDataType() function returns the data type
name for a given byte stream.
The buffer argument is a pointer to the buffer of the data
to be typed.
The size argument is the size of the buffer in bytes.
The opt_name argument can be used to specify a name to be
associated with the buffer. 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 determined.
RETURN VALUE
Upon successful completion, the DtDtsBufferToDataType()
function returns a pointer to a data type name string, or
NULL if no value could be determined.
APPLICATION USAGE
The application should use the DtDtsFreeDataType(3) function
to release the memory for the returned value.
The DtDtsBufferToDataType() function assumes that the buffer
is readable and writable by the user, group and other file
classes and selects a type accordingly. An application
requiring a type based on read-only permissions should use
DtDtsDataToDataType().
