Detailed Description

This example demonstrates the typical integration pattern:

• Create a GOptions object using gphysics::defineOptions().
• Instantiate GPhysics with the shared options.

The example is intentionally minimal and does not attach the resulting physics list to a Geant4 run manager. It is meant as a compilation and usage reference for the module API.

Usage:

./gphysics_example -phys_list FTFP_BERT
./gphysics_example -showPhysics

Function Documentation

main()

int main	(	int	argc,
		char *	argv[] )

This function:

• Parses command line arguments into a GOptions instance configured with gphysics::defineOptions().
• Instantiates GPhysics, which will either:
  • Print available physics lists/constructors if showPhysics is enabled, or
  • Build the reference physics list selected by phys_list.

Parameters

argc	Number of command line arguments.
argv	Array of command line argument strings.

Returns

Process exit code (EXIT_SUCCESS on normal completion).
