elf core dump - reading NT_PRPSINFO

Hi, $ readelf -n core Notes at offset 0x00000274 with length 0x000004c0: Owner Data size Description CORE 0x00000090 NT_PRSTATUS (prstatus structure) CORE 0x0000007c NT_PRPSINFO (prpsinfo structure) CORE 0x000000a0 NT_AUXV (auxiliary vector) CORE 0x0000006c NT_FPREGSET (floating point registers) LINUX 0x00000200 NT_PRXFPREG (user_xfpregs structure) LINUX 0x00000030 Unknown note type: (0x00000200) Does anyone know how to read this NT_PRPSINFO ?
