Decode a binary object description of data space and return a new object handle.
H5S_DECODE (buf )
(unsigned char *buf)
unsigned char *buf IN: Buffer for the data space object to be decoded.
Given an object description of data space in binary in a buffer, H5Sdecode reconstructs the HDF5 data type object and returns a new object handle for it. The binary description of the object is encoded by H5Sencode. User is responsible for passing in the right buffer. The types of data space we address in this function are null, scalar, and simple space. For simple data space, the information of selection, for example, hyperslab selection, is also encoded and decoded. Complex data space has not been implemented in the library.
Returns an object ID(non-negative) if successful; otherwise returns a negative value.
