function::sprint_syms \- Return stack for kernel addresses from string
.SH "SYNOPSIS"

.SH "ARGUMENTS"
.PP
\fIcallers\fR
.RS 4
String with list of hexadecimal (kernel) addresses
.RE
.SH "DESCRIPTION"
.PP
Perform a symbolic lookup of the addresses in the given string, which are assumed to be the result of a prior calls to
\fBstack\fR,
\fBcallers\fR, and similar functions\&.
.PP
Returns a simple backtrace from the given hex string\&. One line per address\&. Includes the symbol name (or hex address if symbol couldn\*(Aqt be resolved) and module name (if found), as obtained from
\fBsymdata\fR\&. Includes the offset from the start of the function if found, otherwise the offset will be added to the module (if found, between brackets)\&. Returns the backtrace as string (each line terminated by a newline character)\&. Note that the returned stack will be truncated to MAXSTRINGLEN, to print fuller and richer stacks use
\fBprint_syms\fR\&.
