NAME
       gelf_update_syminfo - Update additional symbol information in the
       symbol table at the given index


SYNOPSIS
       #include <gelf.h>

       int gelf_update_syminfo (Elf_Data *data, int ndx, GElf_Syminfo *src);


DESCRIPTION
       Copy a class-independent additional symbol information entry from src
       into the SHT_SUNW_syminfo section associated with data at entry index
       ndx.

       data should be associated with an ELF section with type
       SHT_SUNW_syminfo and data type ELF_T_SYMINFO.  These types are
       Sun/Solaris extensions and are not typically used in GNU/Linux ELF
       files.


PARAMETERS
       data   Pointer to an Elf_Data associated with an ELF section with type
              for a section with type SHT_SUNW_syminfo and data type
              ELF_T_SYMINFO.


       ndx    Zero-based index of the entry in data to be updated.


       src    Pointer to a caller-provided additional symbol information
              entry.  Must not be NULL.


RETURN VALUE
       On success, this function returns a non-zero value and updates data
       with src at index ndx.  The section associated with data is flagged
       with ELF_F_DIRTY.  On failure, zero is returned and elf_errno is set.
       If data is NULL, then zero is returned without setting elf_errno.
