POSIX.1 specifies a set of interfaces (functions, header files) for threaded programming commonly known as POSIX threads, or Pthreads.

WebDec 27, 2011 · Let me suggest that you not pass information to threads as values. Using a type of 'long' avoids the logic and compiler errors you are getting with a type of 'int'. 64Bit OS's use 8bytes for a 'void *' and 32bit OS's use only 4bytes, packing data values into pointers sooner or later will be trouble; but it can be done. WebIn many threads implementations, the pthread_t abstract type is implemented as an integer (4 byte) thread ID. In the IBM ® i implementation of Pthreads, the thread ID is a 64-bit integral value and the pthread_t is an abstraction (structure) that contains that value and …
