In the example commands the output binary is specified by the -o argument.
Build list-processes_windows.c with your compiler of choice.
For example, the command for GCC (MinGW) would be:
gcc list-processes_windows.c -o list-processes.exe
Build list-processes_linux.c with your compiler of choice.
For example, the command for GCC would be:
gcc list-processes_linux.c -o list-processes
Build list-processes_freebsd.c with your compiler of choice.
If you get a linker error, make sure you're linking to the util library.
For example, the command for Clang would be:
cc list-processes_freebsd.c -lutil -o list-processes
Build list-processes_macos.m with your compiler of choice.
If you get a linker error, make sure you're linking to the AppKit framework.
For example, the command for Clang would be:
cc list-processes_macos.m -framework AppKit -o list-processes
Build list-processes_bsd.c with your compiler of choice.
If you get a linker error, make sure you're linking to the kvm library.
For example, the command for Clang would be:
cc list-processes_bsd.c -lkvm -o list-processes
