class angr.procedures.libc.strtol.strtol

Bases: SimProcedure

static strtol_inner(s, state, region, base, signed, read_length=None)

Inner parser for strtol-style functions.

Note: all numbers may start with +/- and base 16 may start with 0x.

Parameters:

  • s – the string address/offset

  • state – SimState

  • region – memory, file, etc

  • base – the base to use to interpret the number

  • signed – boolean, true means the result will be signed, otherwise unsigned

  • read_length – int, the number of bytes parsed in strtol

Returns:

(expression, value, num_bytes) where expression is a symbolic boolean indicating success, value is the returned value (set to 0 on failure, or min/max on overflow), and num_bytes is the number of bytes read in the string.
