SYNOPSIS sprint_stack:string(stk:string)

ARGUMENTS stk String with list of hexadecimal (kernel) addresses

DESCRIPTION Perform a symbolic lookup of the addresses in the given string, which is assumed to be the result of a prior call to backtrace.

Returns a simple backtrace from the given hex string. One line per address. Includes the symbol name (or hex address if symbol couldnt be resolved) and module name (if found). Includes the offset from the start of the function if found, otherwise the offset will be added to the module (if found, between brackets).
