String Functions stringf( "xyz", ...) printf( "xyz", ...) strlen("mystring") strsub( const char *string, int offset, int length Definition Since you basically can write books on this, here is an example. Otherwise, it is recommended to purchase a book on C. There are also several examples in Chapter 30, "Installing and Creating Macros," on page 905. This example takes the scriptName parameter and uses the system function echo to print it: extern "C" int system(const char*); const char *z= stringf("echo %s",scriptName); system(z); Returns the length of the string. Extracts a string from another string. Curve Functions The curve functions with implicit time (Linear, CSpline, and so on.) all assume that time is the first argument, so the following statements are identical: LinearV(time,0,1@1,20@20) Linear(0,1@1,20@20) You can, however, adjust the time value explicitly with the V version of each curve type. For more information on spline types, see "More About Splines" on page 316. These are the cycle type codes: • 0 = KeepValue • 1 = KeepSlope • 2 = RepeatValue • 3 = MirrorValue • 4 = OffsetValue Curve Functions biasedGain(x,gain,bias) Linear(cycle, value@key1, value@key2, ...) LinearV(time_value, cycle, value@key1, value@key2, ...) Definition Gives a smoothly-ramped interpolation between 0 and 1, similar to Shake's contrast curve. Gain increases the contrast, and bias offsets the center. Linear interpolation from value at keyframe 1 to value at keyframe 2, and so on. Linear interpolation from value at keyframe 1 to value at keyframe 2, and so on. Chapter 31 Expressions and Scripting 945
