This function allocates memory for a new NcmSParam object and sets its properties to the values from the input arguments.

The name parameter is restricted to the interval [lower_bound , upper_bound ]. scale is an initial step for the statistical algorithms. abstol is the absolute error tolerance of the parameter. ftype indicates if the parameter will be fitted or not.

void
ncm_sparam_clear (NcmSParam **sparam);

Atomically decrements the reference count of sparam by one. If the reference count drops to 0, all memory allocated by sparam is released. Set the pointer to NULL.
