Function elf_getscn() will return a section descriptor for the section at index index in the object denoted by ELF descriptor elf. An error will be signalled if the specified section does not exist.
Function elf_ndxscn() returns the section table index associated with section descriptor scn.
Function elf_newscn() creates a new section and appends it to the list of sections associated with descriptor elf. The library will automatically increment the e_shnum field of the ELF header associated with descriptor elf, and will set the ELF_F_DIRTY flag on the returned section descriptor. For ELF descriptors opened for writing, the ELF library will automatically create an empty section at index zero (SHN_UNDEF) on the first call to elf_newscn().
Function elf_nextscn() takes a section descriptor scn and returns a pointer to the section descriptor at the next higher index. Argument scn is allowed to be NULL, in which case this function will return a pointer to the section descriptor at index 1. If no further sections are present, function elf_nextscn() will return a NULL pointer.
Function elf_ndxscn() returns a valid section table index if successful, or SHN_UNDEF if an error occurs.
