This function informs SOM about the beginning of a new thread of execution (called a task on Windows). The SOM Kernel then performs any needed initialization, including the deferred execution of the SOMInitModule functions found in statically-loaded class libraries. This function must appear near the beginning of all Windows main programs, and may also be used in AIX or OS/2 programs. When used, it supersedes any need to call the somEnvironmentNew function.
A convenience macro, SOM_MainProgram, which combines the execution of this function with the scheduling of the somEnvironmentEnd function during normal program termination, is available for C and C++ programmers.
