########### String module ###########
.. versionadded:: 4.3.0
The String module provides functions for manipulating strings as returned by modules. The strings referenced here are not YARA strings as defined in the strings section of your rule.
.. c:function:: to_int(string)
.. versionadded:: 4.3.0
Convert the given string to a signed integer. If the string starts with "0x"
it is treated as base 16. If the string starts with "0" it is treated base
8. Leading '+' or '-' is also supported.
*Example: string.to_int("1234") == 1234*
*Example: string.to_int("-10") == -10*
*Example: string.to_int("-010") == -8*
.. c:function:: to_int(string, base)
.. versionadded:: 4.3.0
Convert the given string, interpreted with the given base, to a signed
integer. Base must be 0 or between 2 and 36 inclusive. If it is zero then
the string will be intrepreted as base 16 if it starts with "0x" or as base
8 if it starts with "0". Leading '+' or '-' is also supported.
*Example: string.to_int("011", 8) == 9*
*Example: string.to_int("-011", 0) == -9*
.. c:function:: length(string)
.. versionadded:: 4.3.0
Return the length of the string, which can be any sequence of bytes. NULL
bytes included.
*Example: string.length("AXS\x00ERS") == 7*
