These functions are used to update ELF data structures on the underlying ELF descriptor. Class-dependent data structures in the underlying ELF descriptor are updated using the data in the class-independent GElf descriptors and the underlying ELF data structures are marked “dirty”. The conversion process signals an error if the values being copied to the target ELF data structure would exceed representation limits. GElf descriptors are described in
gelf(3).
Function
gelf_update_ehdr() updates the ELF Executable Header with the values in the class-independent executable header
ehdr.
Function
gelf_update_phdr() updates the ELF Program Header structure at index
ndx with the values in the class-independent program header
phdr.
Function
gelf_update_shdr() updates the ELF Section Header structure associated with section descriptor
scn with the values in argument
shdr.
