NAME
nm - print name list of common object file
SYNOPSIS
nm [-o] [-x] [-h] [-v] [-n] [-e] [-f] [-u] [-V]
[-T] file-names
DESCRIPTION
The nm command displays the symbol table of each common
object file file-name. File-name may be a relocatable or absolute
common object file; or it may be an archive of relocatable or absolute
common object files. For each symbol, the following information
will be printed:
N arne The name of the symbol.
Value Its value expressed as an offset or an address depending
on its storage class.
Class Its storage class.
Type Its type and derived type. If the symbol is an instance
of a structure or of a union then the structure or union
tag will be given following the type (e.g. struct-tag). If
the symbol is an array, then the array dimensions will
be given following the type (eg., char[n] [m]). Note that
the object file must have been compiled with the -g
option of the cc(l) command for this information to
appear.
Size Its size in bytes, if available. Note that the object file
must have been compiled with the -g option of the
cc(l) command for this information to appear.
Line The source line number at which it is defined, if available.
Note that the object file must have been compiled
with the -g option of the cc(l) command for this information
to appear.
Section For storage classes static and external, the object file
section containing the symbol (e.g., text, data or bss).
The output of nm may be controlled using the following options:
-o Print the value and size of a symbol in octal instead of
decimal.
Print the value and size of a symbol in hexadecimal
instead of decimal.
-h Do not display the output header data.
-v Sort external symbols by value before they are printed.
-n Sort external symbols by name before they are printed.
-e Print only external and static symbols.
-f Produce full output. Print redundant symbols (.text,
.data and .bss), normally suppressed.
-u Print undefined symbols only.
-x
