Member Enumeration Documentation

◆ EntryType

enum AuxVector::EntryType

Constants describing the type of entry.

On Linux and FreeBSD, running "LD_SHOW_AUXV=1 ./executable" will spew AUX information. Added AUXV prefix to avoid potential conflicts with system- defined macros. For FreeBSD, the numbers can be found in sys/elf_common.h.

Enumerator
AUXV_AT_NULL	End of auxv.
AUXV_AT_IGNORE	Ignore entry.
AUXV_AT_EXECFD	File descriptor of program.
AUXV_AT_PHDR	Program headers.
AUXV_AT_PHENT	Size of program header.
AUXV_AT_PHNUM	Number of program headers.
AUXV_AT_PAGESZ	Page size.
AUXV_AT_BASE	Interpreter base address.
AUXV_AT_FLAGS	Flags.
AUXV_AT_ENTRY	Program entry point.
AUXV_AT_NOTELF	Set if program is not an ELF.
AUXV_AT_UID	UID.
AUXV_AT_EUID	Effective UID.
AUXV_AT_GID	GID.
AUXV_AT_EGID	Effective GID.
AUXV_AT_CLKTCK	Clock frequency (e.g. times(2)).
AUXV_AT_PLATFORM	String identifying platform.
AUXV_AT_HWCAP	Machine dependent hints about processor capabilities.
AUXV_AT_FPUCW	Used FPU control word.
AUXV_AT_DCACHEBSIZE	Data cache block size.
AUXV_AT_ICACHEBSIZE	Instruction cache block size.
AUXV_AT_UCACHEBSIZE	Unified cache block size.
AUXV_AT_IGNOREPPC	Entry should be ignored.
AUXV_AT_SECURE	Boolean, was exec setuid-like?
AUXV_AT_BASE_PLATFORM	String identifying real platforms.
AUXV_AT_RANDOM	Address of 16 random bytes.
AUXV_AT_HWCAP2	Extension of AT_HWCAP.
AUXV_AT_EXECFN	Filename of executable.
AUXV_AT_SYSINFO	Pointer to the global system page used for system calls and other nice things.
AUXV_AT_SYSINFO_EHDR
AUXV_AT_L1I_CACHESHAPE	Shapes of the caches.
AUXV_AT_L1D_CACHESHAPE
AUXV_AT_L2_CACHESHAPE
AUXV_AT_L3_CACHESHAPE
AUXV_FREEBSD_AT_HWCAP	FreeBSD specific AT_HWCAP value.
