.Sh DESCRIPTION
|
||||
This manual page documents convenience routines for handling symbol
|
||||
tables.
|
||||
Two flavors of symbol tables are supported:
|
||||
.Bl -bullet -compact
|
||||
.It
|
||||
.Dq Regular
|
||||
symbol tables supporting insertion, deletion and lookup of entries by
|
||||
name or by value, sorting of entries, and stepping through entries in
|
||||
the table's current traversal order.
|
||||
.It
|
||||
.Dq ELF-centric
|
||||
symbol tables support additional operations for conversions to and
|
||||
from the symbol table format understood by
|
||||
.Lb libelf .
|
||||
.El
|
||||
The default traversal order for a symbol table is the order in which
|
||||
entries were inserted into it.
|
||||
This traversal order may be changed using function
|
||||
.Fn elftc_symbol_table_sort .
|
||||
.Ss Operations on Regular Symbol Tables
|
||||
Regular symbol tables use symbols that are subtypes of
|
||||
.Vt Elftc_Symbol ,
|
||||
as described in the section
|
||||
.Sx "Structure of a Symbol Table Entry"
|
||||
below.

.Pp
|

is NULL, return the last symbol in the current

|
||||
.El
|
||||
.Ss Operations on ELF-centric symbol tables
|
||||
ELF-centric symbol tables use symbols that are subtypes of
|
||||
.Vt Elftc_Elf_Symbol ,
|
||||
as described in the section
|
||||
.Sx "Structure of a Symbol Table Entry"
|
||||
below.
|
||||
.Pp
|
||||
In addition to the operations on regular symbol tables listed above,
|
||||
these symbol tables may be used with the following additional
|
||||
functions.
|
||||
.Pp
|
||||
The function
|
||||
.Fn elftc_elf_symbol_table_from_section
|
||||
builds a symbol table from the contents of an ELF section.
|
||||
The argument
|
||||
.Ar symscn
|
||||
should reference an ELF section of type
|
||||
.Dv SHT_SYMTAB
|
||||
or
|
||||
.Dv SHT_DYNSYM .
|
||||
The argument
|
||||
.Ar strscn
|
||||
should reference an ELF section of type
|
||||
.Dv SHT_STRTAB
|
||||
containing the string table associated wit section
|
||||
.Ar symscn .
|
||||
.Ss Structure of a Symbol Table Entry
|
||||
The symbol tables managed by
|
||||
.Lb libelftc
|
||||
are collections of symbol table entries.
|
||||
Each entry should be a subtype of one of the
|
||||
.Vt Elftc_Symbol
|
||||
or
|
||||
.Vt Elftc_Elf_Symbol
|
||||
types.
|
||||
In other words, each entry should have an
|
||||
.Vt Elftc_Symbol
|
||||
or
|
||||
.Vt Elftc_Elf_Symbol
|
||||
structure as its first member, before any application specific
|
||||
fields.
|
||||
For example:
|
||||
.Bd -literal -offset indent
|
||||
struct _MySymbol {
|
||||
Elftc_Symbol sym_base;
|
||||
... other application-specific fields ...
|
||||
};
|
||||
.Ed
|
||||
.Pp
|
||||
The size of the combined entry is indicated to the library
|
||||
at the time of creating a new symbol table.
|
||||
Applications may then cast the returned pointers from these
|
||||
routines to the appropriate type:
|
||||
.Bd -literal -offset indent
|
||||
struct _MySymbol *mysym;
|
||||
|
||||
mysym = (struct _MySymbol *) elftc_symbol_table_lookup(table,
|
||||
name);
|
||||
.Ed
|
||||
.Pp
|
||||
The
|
||||
.Vt Elftc_Symbol
|
||||
type has two public fields:
|
||||
.Bl -tag -width ".Va sym_value" -compact -offset indent
|
||||
.It Va sym_name
|
||||
Points to a NUL-terminated string containing the symbol's name.
|
||||
The application should not change the value of this field.
|
||||
.It Va sym_value
|
||||
The value associated with this symbol.
|
||||
This field is entirely under the application's control.
|
||||
.El
|
||||
.Pp
|
||||
The
|
||||
.Vt Elftc_Elf_Symbol
|
||||
type has two public fields:
|
||||
.Bl -tag -width ".Va sym_value" -compact -offset indent
|
||||
.It Va sym_name
|
||||
Points to a NUL-terminated string containing the symbol's name.
|
||||
The application should not change the value of this field.
|
||||
.It Va sym_elf
|
||||
A structure of type
|
||||
.Vt Gelf_Sym
|
||||
containing ELF symbol information.
|
||||
This field is entirely under the application's control.
|
||||
.El
|
||||
.Ss Symbol Search Rules
|
||||
During lookups, symbols are looked up first in the symbol table passed in
|
||||
to the
|
||||
.Fn elftc_symbol_table_lookup
|
||||
function.
|
||||
If the specified symbol is not found, and if the symbol table has a
|
||||
parent, then the search continues recursively up the chain of parent
|
||||
symbol tables till either a matching symbol is found or till there are
|
||||
no more parent symbol tables to search in.
|
||||
.Pp
|
||||
Insertions and deletion only work on the specified symbol table and
|
||||
do not recurse into parent symbol tables.
|
||||
.Ss Memory Management
|
||||
The
|
||||
.Lb libelftc
|
||||
manages its memory allocations.
|
||||
Applications should not free the pointers returned by the
|
||||
API documented in this manual page.
|
||||
.Sh RETURN VALUES
|
||||
Function
|
||||
.Fn elftc_symbol_table_count
|
||||
returns a count of the number of symbol table entries as an unsigned
|
||||
value.

||||
.Pp

||||

|
||||
.Fn elftc_symbol_table_create ,
|
||||
.Fn elftc_symbol_table_create_nested

|
||||
return a pointer to an opaque structure of type

||||
on success, or return NULL in case of an error.

specified traversal direction.

The function
