These functions return a pointer to the ELF Section Header data structure
associated with section descriptor
scn.
Function
elf32_getshdr() retrieves a pointer to an
Elf32_Shdr structure. Section descriptor
scn must be associated with an ELF descriptor
of class
ELFCLASS32
.
Function
elf64_getshdr() retrieves a pointer to an
Elf64_Shdr structure. Section descriptor
scn must be associated with an ELF descriptor
of class
ELFCLASS64
.
Function
gelf_getshdr() copies the values in the
section header associated with argument
scn
to the structure pointed to be argument
dst.
The
GElf_Shdr data structure is described in
gelf(3).
Functions
elf32_getshdr() and
elf64_getshdr() return a valid pointer to the
appropriate section header on success or NULL if an error was encountered.
Function
gelf_getshdr() returns argument
dst if successful, or NULL if an error was
encountered.
These functions may fail with the following errors:
-
-
- [
ELF_E_ARGUMENT
]
- Arguments scn or
shdr were NULL.
-
-
- [
ELF_E_ARGUMENT
]
- Argument scn was not
associated a descriptor for an ELF object.
-
-
- [
ELF_E_CLASS
]
- The ELF class associated with the section descriptor
scn did not match the class expected by
the API.
