Error checking mechanism.
Purse of this mechanism is to inform user about problems that occured during executaion of library functions. Mechanism is similar to linux errno variable. When the problem raise, the information about it is stored in library buffer. This information consists of error family, and textual description. Example of usage:
syschar = oval_probe_object_eval (pctx, object); if (syschar == NULL && oscap_err()) { printf("Error: (%d) %s\n", oscap_err_family(), oscap_err_desc()); } oscap_clearerr()
