NAME
nm - display name list (symbol table)
SYNOPSIS
nm [ -agnoprumxjlfPA [ s segname sectname ]] [ - ] [ -t format ] [[ -arch
arch_flag ]...] [ file ... ]
DESCRIPTION
Nm displays the name list (symbol table) of each object file in the argument
list. If an argument is an archive, a listing for each object file in the ar-
chive will be produced. File can be of the form libx.a(x.o), in which case
only symbols from that member of the object file are listed. (The parentheses
have to be quoted to get by the shell.) If no file is given, the symbols in
a.out are listed.
Each symbol name is preceded by its value (blanks if undefined). Unless the
-m option is specified, this value is followed by one of the following charac-
ters, representing the symbol type: U (undefined), A (absolute), T (text sec-
tion symbol), D (data section symbol), B (bss section symbol), C (common sym-
bol), - (for debugger symbol table entries; see -a below), S (symbol in a sec-
tion other than those above), or I (indirect symbol). If the symbol is local
(non-external), the symbol's type is instead represented by the corresponding
lowercase letter. A lower case u in a dynamic shared library indicates a
undefined reference to a private external in another module in the same
library.
If the symbol is a Objective C method, the symbol name is +-[Class_name(cate-
gory_name) method:name:], where `+' is for class methods, `-' is for instance
methods, and (category_name) is present only when the method is in a category.
The output is sorted alphabetically by default.
