ReturnArguments
A C gateway function which returns the various variables.
Syntax
ReturnArguments(pvApiCtx);
Description
ReturnArguments(pvApiCtx) will return the various variables declared through AssignOutputVariable(pvApiCtx, X).
Examples
This example takes a matrix of doubles as input and returns:
the number of lines (first output argument)
the number of rows (second output argument)
#include "api_scilab.h" int sci_mysizedouble(char * fname, void* pvApiCtx) { SciErr sciErr; int m_in_row; int n_in_col; int* piAddr = NULL; double* pdblData = NULL; sciErr = getVarAddressFromPosition(pvApiCtx, 1, &piAddr); if(sciErr.iErr) { printError(&sciErr, 0); return 0; } /* get dimensions */ sciErr = getMatrixOfDouble(pvApiCtx, piAddr, &m_in_row, &n_in_col, &pdblData); if(sciErr.iErr) { printError(&sciErr, 0); return 0; } sciErr = createMatrixOfInteger32(pvApiCtx, nbInputArgument(pvApiCtx) + 1, 1, 1, &m_in_row); // the m_in_row parameter handles the number of lines of the matrix sent as argument sciErr = createMatrixOfInteger32(pvApiCtx, nbInputArgument(pvApiCtx) + 2, 1, 1, &m_in_row); // store a same value, but will neither be used nor returned to Scilab sciErr = createMatrixOfInteger32(pvApiCtx, nbInputArgument(pvApiCtx) + 3, 1, 1, &n_in_col); // the n_in_col parameter handles the number of columns of the matrix sent as argument AssignOutputVariable(pvApiCtx, 1) = nbInputArgument(pvApiCtx) + 1; // We set the parameter "nbInputArgument(pvApiCtx) + 1" as an output argument AssignOutputVariable(pvApiCtx, 2) = nbInputArgument(pvApiCtx) + 3; // We set the parameter "nbInputArgument(pvApiCtx) + 3" as an output argument ReturnArguments(pvApiCtx); return 0; }
