`void *XPRMgetnextpkgparam(XPRMmodel model, void *ref, const char **name, const char **desc, int *type);`
Arguments

model | Reference to a model
ref | Reference pointer or NULL
name | Returned name of the control parameter
desc | Reserved for future use (should be NULL
type | Returned type of the control parameter

Return value
Reference pointer for the next call to XPRMgetnextpkgparam.
Further information
This function returns the next control parameter of the given package (a model cannot publish control parameters). The second parameter is used to store the current location in the table of control parameters; if this parameter is NULL, the first control parameter of the table is returned. This function returns NULL if it is called with the reference to the last parameter of the given module. Otherwise, the returned value can be used as the input parameter ref to get the following control parameter and so on. The type can be decoded using the macro XPRM_TYP. Moreover, the bits XPRM_CPAR_READ and XPRM_CPAR_WRITE are set to indicate if the parameter can be read or written respectively (using getparam and setparam).
