    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 Vt Elf32_Syminfo and Vt Elf64_Syminfo records in an ELF object.

    Argument data is an Vt 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 Vt 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:

    Bq Er ELF_E_ARGUMENT
    Arguments data or syminfo were NULL.
    Bq Er ELF_E_ARGUMENT
    Argument ndx was less than zero or larger than the number of symbols in the data descriptor.
    Bq Er ELF_E_ARGUMENT
    Data descriptor data was not associated with a section containing symbol information.
