GELF_GETSYMINFO(3) FreeBSD Library Functions Manual GELF_GETSYMINFO(3)
NAME gelf_getsyminfo, gelf_update_syminfo - read and update symbol information
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- dependent 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 retrieved or updated. The class-independent GElf_Syminfo structure is described 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 argument 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 successful, or NULL in case of an error. Function gelf_update_syminfo() returns 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 number 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 associated with an ELF object with an unsupported version.
