static YCPValue Eval ( const YCPValue &  v  )  [static]

eval Evaluate a YCP value. See also the builtin ``, which is kind of the counterpart to eval.

eval (``(1+2)) -> 3

static YCPString Getenv ( const YCPString &  name  )  [static]

getenv Change or add an environment variable The getenv(variable) function returns the value of variable from environment. If variable doesn't exist the value is NULL.

Parameters:
string name
Returns:
string value getenv ("USER") -> "root" getenv ("LC_CTYPE") -> "en_US.UTF-8"

static YCPInteger Random ( const YCPInteger &  max  )  [static]

random Random number generator. Returns a random integer in the interval [0,MAX). srandom must be activated to get really random numbers.

Parameters:
integer MAX
Returns:
integer Returns integer in the interval [0,MAX). random(100) -> 82 random(100) -> 36

any PAR1
any PAR2
any ...
Returns:
string sformat ("%2 is greater %% than %1", 3, "five") -> "five is greater % than 3"
