-.Dt GELF_UPDATE_EHDR 3
-.Sh NAME
-.Nm gelf_update_ehdr ,
-.Nm gelf_update_phdr ,
-.Nm gelf_update_shdr
-.Nd update underlying ELF data structures
-.Sh LIBRARY
-.Lb libelf
-.Sh SYNOPSIS
-.In gelf.h
-.Ft int
-.Fn gelf_update_ehdr "Elf *elf" "GElf_Ehdr *ehdr"
-.Ft int
-.Fn gelf_update_phdr "Elf *elf" "int ndx" "GElf_Phdr *phdr"
-.Ft int
-.Fn gelf_update_shdr "Elf_Scn *scn" "GElf_Shdr *shdr"
-.Sh DESCRIPTION
-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
-.Dq 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
-.Xr gelf 3 .
-.Pp
-Function
-.Fn gelf_update_ehdr
-updates the ELF Executable Header with the values in the
-class-independent executable header
-.Ar ehdr .
-.Pp
-Function
-.Fn gelf_update_phdr
-updates the ELF Program Header structure at index
-.Ar ndx
-with the values in the class-independent program header
-.Ar phdr .
-.Pp
-Function
-.Fn gelf_update_shdr
-updates the ELF Section Header structure associated with section
-descriptor
-.Ar scn
-with the values in argument
-.Ar shdr .
-.Sh RETURN VALUES
-These functions return a non-zero integer on success, or zero in case
-of an error.
-.Sh ERRORS
-These functions may fail with the following errors:
-.Bl -tag -width "[ELF_E_RESOURCE]"
-.It Bq Er ELF_E_ARGUMENT
-Arguments
-.Ar elf ,

-were NULL.
-.It Bq Er ELF_E_ARGUMENT
-Argument
-.Ar elf
-was not a descriptor for an ELF object.
-.It Bq Er ELF_E_ARGUMENT
-Argument
-.Ar elf
-had an unsupported ELF class.
-.It Bq Er ELF_E_ARGUMENT
-Argument
-.Ar ndx
-exceeded the number of entries in the program header table.
-.It Bq Er ELF_E_ARGUMENT
-Section descriptor
-.Ar scn
-was not associated with an ELF descriptor.
-.It Bq Er ELF_E_MODE
-ELF descriptor
-.Ar elf
-was not opened for writing or updating.
-.It Bq Er ELF_E_RESOURCE
-An out of memory condition was detected.
