sg_set_error() sets the occurred error condition
together with an argument. The argument is usually descriptive, eg.
the file name which failed to open.
sg_set_error_with_errno() sets the occurred error
condition together with an argument and the value of the system
libraries errno value. The argument is usually
descriptive, eg. the name of the failed sysctl()
call.
sg_set_error_with_errno_code() sets the occurred
error condition together with an argument and an error value of a
system library call which doesn't set the errno
value (eg. the pthread_* calls). The argument is usually descriptive,
eg. the name of the mutex failed to get locked.
sg_clear_error() clears the current error
condition.
