GELF_GETSYMINFO(3) BSD Library Functions Manual GELF_GETSYMINFO(3) NAME gelf_getsyminfo, gelf_update_syminfo -- read and update symbol informa- tion LIBRARY ELF Access Library (libelf, -lelf) SYNOPSIS #include <gelf.h> GElf_Syminfo * gelf_getsyminfo(Elf_Data *data, int ndx, GElf_Syminfo *syminfo); int gelf_update_syminfo(Elf_Data *data, int ndx, GElf_Syminfo *syminfo); DESCRIPTION These convenience functions are used to retrieve and update class-depen- dent Elf32_Syminfo and Elf64_Syminfo records in an ELF object. Argument data is an Elf_Data descriptor associated with a section of type SHT_SUNW_syminfo. Argument ndx is the index of the record being re- trieved or updated. The class-independent GElf_Syminfo structure is de- scribed in gelf(3). Function gelf_getsyminfo() retrieves class-dependent record at index ndx in data buffer data and copies it to the destination pointed to by argu- ment syminfo after translation to class-independent form. Function gelf_update_syminfo() converts the class-independent record pointed to by argument syminfo to class-dependent form, and writes it to the record at index ndx in the data buffer described by argument data. RETURN VALUES Function gelf_getsyminfo() returns the value of argument syminfo if suc- cessful, or NULL in case of an error. Function gelf_update_syminfo() re- turns a non-zero value if successful, or zero in case of an error. ERRORS These functions may fail with the following errors: [ELF_E_ARGUMENT] Arguments data or syminfo were NULL. [ELF_E_ARGUMENT] Argument ndx was less than zero or larger than the num- ber of symbols in the data descriptor. [ELF_E_ARGUMENT] Data descriptor data was not associated with a section containing symbol information. [ELF_E_VERSION] The Elf_Data descriptor denoted by argument data is as- sociated with an ELF object with an unsupported ver- sion.
