What's the maximum process ID? RRS feed

  • 问题

  • I'm trying to migrate a set of unix codes to windows platform.

    It is said PID ranges from 0 to 0x7fff in unix and PID was stored in an int32 datatype variable.

    However, i find a definition "int  _getpid(void);"in process.h.

    Do i need to expand PID from int32 to int64? What would happen if i continue using int32 datatype?
