Function pamoja_profile_reads_unit 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn pamoja_profile_reads_unit(
    profile: *const PamojaProfile,
) -> *mut PamojaString

Returns the unit a profile’s numbers are in, such as celsius.

Arguments

• profile - the profile.

Returns

A null-terminated UTF-8 string, which the caller must release with pamoja_string_free, or null if the profile does not say what it reads or profile is null. The two cases are told apart by pamoja_last_error_message, which is set only for a null handle.

Safety

profile must be a live handle from a call that produced one, or null.
