STRUCT USER_REGSET_V(9) Machine State STRUCT USER_REGSET_V(9)NAME
struct_user_regset_view - available regsets
SYNOPSIS
struct user_regset_view {
const char * name;
const struct user_regset * regsets;
unsigned int n;
u32 e_flags;
u16 e_machine;
u8 ei_osabi;
};
MEMBERS
name
Identifier, e.g. UTS_MACHINE string.
regsets
Array of n regsets available in this view.
n
Number of elements in regsets.
e_flags
ELF header e_flags value written in core dumps.
e_machine
ELF header e_machine EM_* value written in core dumps.
ei_osabi
ELF header e_ident[EI_OSABI] value written in core dumps.
DESCRIPTION
A regset view is a collection of regsets (struct user_regset, above). This describes all the state of a thread that can be seen from a
given architecture/ABI environment. More than one view might refer to the same struct user_regset, or more than one regset might refer to
the same machine-specific state in the thread. For example, a 32-bit thread's state could be examined from the 32-bit view or from the
64-bit view. Either method reaches the same thread register state, doing appropriate widening or truncation.

elf32_getehdr(3ELF) ELF Library Functions elf32_getehdr(3ELF)NAME
elf32_getehdr, elf32_newehdr, elf64_getehdr, elf64_newehdr - retrieve class-dependent object file header
SYNOPSIS
cc [ flag ... ] file ... -lelf [ library ... ]
#include <libelf.h>
Elf32_Ehdr *elf32_getehdr(Elf *elf);
Elf32_Ehdr *elf32_newehdr(Elf *elf);
Elf64_Ehdr *elf64_getehdr(Elf *elf);
Elf64_Ehdr *elf64_newehdr(Elf *elf);
DESCRIPTION
For a 32-bit class file, elf32_getehdr() returns a pointer to an ELF header, if one is available for the ELF descriptor elf. If no header
exists for the descriptor, elf32_newehdr() allocates a clean one, but it otherwise behaves the same as elf32_getehdr(). It does not allo-
cate a new header if one exists already. If no header exists for elf32_getehdr(), one cannot be created for elf32_newehdr(), a system error
occurs, the file is not a 32-bit class file, or elf is NULL, both functions return a null pointer.
For the 64-bit class, replace 32 with 64 as appropriate.
The header includes the following members:
unsigned char e_ident[EI_NIDENT];
Elf32_Half e_type;
Elf32_Half e_machine;
Elf32_Word e_version;
Elf32_Addr e_entry;
Elf32_Off e_phoff;
Elf32_Off e_shoff;
Elf32_Word e_flags;
Elf32_Half e_ehsize;
Elf32_Half e_phentsize;
Elf32_Half e_phnum;
Elf32_Half e_shentsize;
Elf32_Half e_shnum;
Elf32_Half e_shstrndx;
The elf32_newehdr() function automatically sets the ELF_F_DIRTY bit. See elf_flagdata(3ELF).
An application can use elf_getident() to inspect the identification bytes from a file.
An application can use elf_getshnum() and elf_getshstrndx() to obtain section header information. The location of this section header
information differs between standard ELF files to those that require Extended Sections.
