Name: H5Tis_variable_str
Signature:
htri_t H5Tis_variable_str( hid_t dtype_id )

Purpose:
Determines whether datatype is a variable-length string.

Description:
H5Tis_variable_str determines whether the datatype identified in dtype_id is a variable-length string.

This function can be used to distinguish between fixed and variable-length string datatypes.

Parameters:
hid_t dtype_id     IN: Datatype identifier.

Returns:
Returns a positive value if the specified datatype is a variable-length string.
Returns 0 if the specified datatype is not a variable-length string.
Returns a negative value when the function fails.
