Regular API function

simGetStackStringValue

Description	Tries to retrieve the value at the top of the stack, if that value is a string. See also the other stack functions.
C/C++ synopsis	simChar* simGetStackStringValue(simInt stackHandle,simInt* stringSize)
C/C++ parameters	stackHandle: a stack handle obtained with simCreateStack. stringSize: a pointer to a location receiving the size of the string. Can be nullptr if the string size is of no interest.
C/C++ return value	In case of an error, the return value is nullptr and stringSize will be set to -1 (if stringSize is not nullptr). If the stack item is not a string, the return value is nullptr and stringSize will be set to 0 (if stringSize is not nullptr). If the stack item is a string, the return value is not nullptr, and stringSize will be the size of the string buffer (if stringSize is not nullptr). In that case, the user is in charge of releasing the returned buffer with simReleaseBuffer.
