The meaning of _t in intptr_t [duplicate]
Generally, the suffix of _t refers to typedef, and _s to a structure. There is no difference to the compiler, but for the benefit of users reading the code. This was once a common practice to apply such suffixes, but is now discouraged due to conflicts with POSIX & basic human confusion. Other similar discussions

Example:
