DtDtsBufferToAttriUNIXVSystem)V (1 DtDtsBufferToAttributeValue(3)
NAME
DtDtsBufferToAttributeValue - get a single data attribute
value for a byte stream
SYNOPSIS
#include <Dt/Dts.h>
char *DtDtsBufferToAttributeValue(const void *buffer,
const int size,
const char *attr_name,
const char *opt_name);
DESCRIPTION
The DtDtsBufferToAttributeValue() function returns a data
attribute value 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 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 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
DtDtsBufferToAttributeValue() 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 DtDtsBufferToAttributeValue() 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().
