sg_set_error, sg_set_error_with_errno, sg_set_error_with_errno_code, sg_clear_error - sets the error

sg_set_error() sets the occurred error condition together with an argument. The argument is  usually  de‐
       scriptive, 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.

       sg_set_error,  sg_set_error_with_errno,  sg_set_error_with_errno_code,  sg_clear_error  -  sets the error
       condition
