2290 * DESCRIPTION: | |
2291 * This function looks up for the command and each children AVP definitions in the dictionary. | |
2292 * If the dictionary definition is found, avp_model is set and the value of the AVP is interpreted accordingly and: | |
2293 * - for grouped AVPs, the children AVP are created and interpreted also. | |
2294 * - for numerical AVPs, the value is converted to host byte order and saved in the avp_value field. | |
2295 * - for octetstring AVPs, the string is copied into a new buffer and its address is saved in avp_value. | |
2296 * If the dictionary definition is not found, avp_model is set to NULL and | |
2297 * the content of the AVP is saved as an octetstring in an internal structure. avp_value is NULL. | |
2298 * As a result, after this function has been called, there is no more dependency of the msg object to the message buffer, that is be freed. | |
2299 * | |
2300 * RETURN VALUE: | |
2301 * 0 : The message has been fully parsed as described. | |
2302 * EINVAL : The msg parameter is invalid for this operation. | |
2303 * ENOMEM : Unable to allocate enough memory to complete the operation. | |
