SYNOPSIS

           returnstr:string(format:long)

ARGUMENTS

       format

DESCRIPTION

       This function is used by the nd_syscall tapset, and returns a string. Set format equal to
       1 for a decimal, 2 for hex, 3 for octal.

       Note that this function should only be used in dwarfless probes (i.e.
       'kprobe.function(“foo”)'). Other probes should use return_str.
