I see in include/sys/types.h on Solaris 9:
#if defined(_LP64) || defined(_I32LPx)
typedef uint_t nlink_t; /* file link type */
typedef int pid_t; /* process id type */
typedef ulong_t nlink_t; /* (historical version) */
typedef long pid_t; /* (historical version) */
I am confused why you are seeing long for pid_t? What is your Solaris
system information? If Solaris needs adjustments, there are a lot of
place we print getpid().
