getAllocatedSinglePoly Get single polynomial variable.

## Syntax

    int getAllocatedSinglePoly(void* _pvCtx, int* _piAddress, int* _piNbCoef, double** _pdblReal)

    int getAllocatedNamedSinglePoly(void* _pvCtx, const char* _pstName, int* _piNbCoef, double** _pdblReal)

## Arguments

_pvCtx

  Scilab environment pointer, pass in "pvApiCtx" provided by api_scilab.h.

_piAddress

  Address of the Scilab variable.

_pstName

  Name of the variable for "named" functions.

_piNbCoef

  Returns number of coefficient.

_pdblReal

  Return array of double.

## Return value

if successful 0, otherwise print error(s) message(s) in the Scilab console and returns first error number.
