#pragma priority (C++ only)
In IBM® XL C/C++ for AIX® 16.1.0 or earlier releases, #pragma priority specifies the priority level for the initialization of static objects.
IBM Open XL C/C++ for AIX 17.1.3
does not support #pragma priority. However, IBM Open XL C/C++ for AIX 17.1.3 supports the
__attribute__((init_priority)) attribute that provides a similar function to
#pragma priority, with which you can specify non-default priorities for static
objects in source code. However, the value range of the priority level in
__attribute__((init_priority)) is different from that of #pragma
priority. As a result, there is no guarantee of relative ordering between the objects
compiled with IBM Open XL C/C++ for AIX 17.1.3 and the
objects compiled with IBM XL C/C++ for AIX
16.1.0 or earlier
releases.
