SWU_cArrayToList

SWU_cArrayToList is a library procedure which allows users to convert a C array of type long, integer, float or double to a Tcl list. The input data is a C array ID.

package require SWU

SWU_cArrayToList C_array_ID

C array ID: An ID returned by the SAA_Alloc*, after it allocates memory for a C array.

Return Value

If the procedure succeeds then it returns a list of values of the element's C array, otherwise an error message string is returned on the Tk console command line.

Side Effects

None.

Examples

set curScene [SAA_AllocScene]

Scene1

SAA_sceneGetCurrent $curScene

package require SW

1.0

set nurbsID [SW_name2Element nurbs1 $curScene]

Elem4

SAA_nurbsCurveGetNbKnots $curScene $nurbsID nb_knots

set nb_knots

6

set knotsArrayID [SAA_AllocDouble $nb_knots]

DoubleArray5

SAA_nurbsCurveGetKnots $curScene $nurbsID 0 0 $nb_knots $knotsArrayID

set knotsList [SWU_cArrayToList $knotsArrayID]

1.345 2.456 7.876 0.876 4.789 5.456

puts $knotsList

1.345 2.456 7.876 0.876 4.789 5.456

This example gets the nurbs curve element, defines the number of knots for the nurbs curve, allocates a C array of doubles, fills this C array with the knots values, converts the knots array to a Tcl list and prints out the knots values.
