gelf_update_symshndx

 - read and update symbol information using extended section indices

 

LIBRARY

Lb libelf

 

SYNOPSIS

DESCRIPTION

Argument symdata is an Vt Elf_Data descriptor associated with a section of type SHT_SYMTAB Argument xndxdata is an Vt Elf_Data descriptor associated with a section of type SHT_SYMTAB_SHNDX Argument ndx is the index of the symbol table entry being retrieved or updated. Argument sym is a pointer to a class-independent Vt GElf_Sym structure. Vt GElf_Sym structures are described in detail in gelf(3).

Function gelf_getsymshndx ();
retrieves symbol information at index ndx from the data descriptor specified by argument symdata and stores in class-independent form in argument sym In addition it retrieves the extended section index for the symbol from data buffer xndxdata and stores it into the location pointed to by argument xndxptr

Function gelf_update_symshndx ();
updates the underlying symbol table entry in data descriptor symdata with the information in argument sym In addition it sets the extended section index in data buffer xndxdata to the value of argument xndx  

RETURN VALUES

Function gelf_update_symshndx ();
returns a non-zero value if successful, or zero in case of an error.
