Function Documentation

int GetClipboard

(

std::string &

str

)

Standard implementation of getopt(3).

One extension: If the first character of the optionsstring is a ':' the error return for 'argument required' is a ':' not a '?'. This makes it easier to differentiate between an 'illegal option' and an 'argument required' error.

Paste text from the clipboard

void InitSyncRand

(

void

)

long isqrt

(

long

num

)

Compute a square root using ints

Uses John Halleck's method, see http://www.cc.utah.edu/~nahaj/factoring/isqrt.legalize.c.html

Parameters:

num

Calculate the square root of this number

Returns:

The integer square root.

int SyncRand

(

int

max

)

Syncron rand.

Synchronized random number.

Parameters:

max

Max value of random number to return

Definition at line 84 of file util.cpp.

References SyncRand().

int SyncRand

(

void

)

Syncron rand.

Synchronized random number.

Note:

This random value must be same on all machines in network game. Very simple random generations, enough for us.
