Default Output Format - SOM
If the default (neither the -p nor the -P option) output format is specified, each symbol has the following
columns, separated by vertical bars (|). The default for numbers is decimal (-d
or -t d).
If decimal:
"%20s|%10d|%6s|%7s|%s",
name, value, scope, type, subspace
If octal:
"%20s|%012o|%6s|%7s|%s",
name, value, scope, type, subspace
If hexadecimal:
"%20s|0x%08x|%6s|%7s|%s",
name, value, scope, type, subspace
Default Output Format - ELF
If the default (neither the
-p nor the -P option) output format is specified, each symbol has the following
columns, separated by vertical bars (|). The default for numbers is decimal (-d
or -t d).
If decimal:
"[%u]%s|%22llu|%8u|%s|%s|%1d|%s|%s",
index, value, size, type, bind, O, shndx, name
If octal:
"[%u]%s|%022llo|%010o|%s|%s|%1o|%s|%s",
index, value, size, type, bind, O, shndx, name
If hexadecimal:
"[%u]%s|0x%016llx|0x%08x|%s|%s|%1x|%s|%s",
index, value, size, type, bind, O, shndx, name
The descriptions are explained below:
name The name of the symbol.
value Its value expressed as an offset or an address depending on its storage class.
scope The scope of the symbol (
external, sdef, static,orundefined). The sdef
