The pthread_getcpuclockid() function is declared in the include file /usr/include/pthread.h. The only difference between the two "versions" of Solaris 11.4 is that the newer version has a declaration and the older one does not. However, _POSIX_THREAD_CPUTIME is defined in the /usr/include/unistd.h file as -1 in the UNIX 03 block of options that are not supported in Solaris 11.4. /* Unsupported UNIX 03 options */ #if defined(_XPG6) .. #define _POSIX_THREAD_CPUTIME (-1) .. #endif An explanation of that definition can be found here: https://docs.oracle.com/cd/E88353_01/html/E37842/unistd-3head.html "If a symbolic constant is defined with the value -1, the option is not supported. Headers, data types, and function interfaces required only for the option need not be supplied. An application that attempts to use anything associated only with the option is considered to be requiring an extension. If a symbolic constant is defined with a value greater than zero, the option is always supported when the application is executed. All headers, data types, and functions are present and operate as specified. If a symbolic constant is defined with the value zero, all headers, data types, and functions are present. The application can check at runtime to see whether the option is supported by calling fpathconf(), pathconf(), or sysconf() with the indicated name parameter." -- Miroslav Zagorac What can change the nature of a man?
