gnokii error type

[A. Andria]

Hi Pawel,

Something that I know in outbox table is :

field processed = 0, it's mean sms pending (not processed yet by the smsd)
field processed = 1, it's mean sms has been processed by smsd (sms sent)

by default, field error filled by -1 value. What is other posibility 
value on field error and what's  the meaning ?

How do I know what's the error, if the sms processed=1, mobile voucher 
decrease, but the recipient did not receive a message ?

I've read the include/gnokii/error.h but did not find error code and the 
meaning of the error. I found only :

/* General codes */
       GN_ERR_NONE = 0,                /* No error. */
