GELF_GETCHDR(3) FreeBSD Library Functions Manual GELF_GETCHDR(3) NAME elf32_getchdr, elf64_getchdr, gelf_getchdr - retrieve the compression header of a section LIBRARY ELF Access Library (libelf, -lelf) SYNOPSIS #include <libelf.h> Elf32_Chdr * elf32_getchdr(Elf_Scn *s); Elf64_Chdr * elf64_getchdr(Elf_Scn *s); #include <gelf.h> GElf_Chdr * gelf_getchdr(Elf_Scn *scn, GElf_Chdr *chdr); DESCRIPTION These functions return a pointer to the ELF Compression Header data structure associated with section descriptor scn. Function elf32_getchdr() retrieves a pointer to an Elf32_Chdr structure. Section descriptor scn must be associated with an ELF descriptor of class ELFCLASS32. Function elf64_getchdr() retrieves a pointer to an Elf64_Chdr structure. Section descriptor scn must be associated with an ELF descriptor of class ELFCLASS64. Function gelf_getchdr() copies the values in the compression header associated with argument scn to the structure pointed to be argument dst. The GElf_Chdr data structure is described in gelf(3). RETURN VALUES Functions elf32_getchdr() and elf64_getchdr() return a valid pointer to the appropriate compression header on success or NULL if an error was encountered. Function gelf_getchdr() returns argument dst if successful, or NULL if an error was encountered. ERRORS These functions may fail with the following errors: [ELF_E_INVALID_SECTION_FLAGS] Arguments scn has invalid flags. [ELF_E_INVALID_SECTION_TYPE] Argument scn has invalid type. [ELF_E_NOT_COMPRESSED] Argument scn is not compressed. SEE ALSO elf(3), elf_getscn(3), gelf(3), FreeBSD 14.1-RELEASE-p8 October 23, 2020 FreeBSD 14.1-RELEASE-p8
