Quoting from the libc manual:
The pid_t data type is a signed integer type which is capable of
representing a process ID. In the GNU C Library, this is an int.

data types that ends with "_t", are usually a defined type variable in C and C++ as an unwritten law.
according to that law, "pid_t" is a data type which is defined somewhere else but "int" a standard type; so to know the differences you need to know how "pid_t" is defined.

defined types are usually used to make the code more clear. using them also makes it more easier to change the code.
