| 18 | NAME |
| 19 | -------------------------------------------------------------------------------------------- |
| 20 | |
| 21 | rmr_str2meid |
| 22 | |
| 23 | SYNOPSIS |
| 24 | -------------------------------------------------------------------------------------------- |
| 25 | |
| 26 | |
| 27 | :: |
| 28 | |
| 29 | #include <rmr/rmr.h> |
| 30 | int rmr_str2meid( rmr_mbuf_t* mbuf, unsigned char* src, int len ) |
| 31 | |
| 32 | |
| 33 | |
| 34 | DESCRIPTION |
| 35 | -------------------------------------------------------------------------------------------- |
| 36 | |
| 37 | The rmr_str2meid function will copy the string pointed to by |
| 38 | src to the managed entity ID (meid) field in the given |
| 39 | message. The field is a fixed length, gated by the constant |
| 40 | RMR_MAX_MEID and if string length is larger than this value, |
| 41 | then **nothing** will be copied. (Note, this differs slightly |
| 42 | from the behaviour of the lrmr_bytes2meid() function.) |
| 43 | |
| 44 | RETURN VALUE |
| 45 | -------------------------------------------------------------------------------------------- |
| 46 | |
| 47 | On success, the value RMR_OK is returned. If the string |
| 48 | cannot be copied to the message, the return value will be one |
| 49 | of the errors listed below. |
| 50 | |
| 51 | ERRORS |
| 52 | -------------------------------------------------------------------------------------------- |
| 53 | |
| 54 | If the return value is not RMR_OK, then it will be set to one |
| 55 | of the values below. |
| 56 | |
| 57 | |
| 58 | |
| 59 | RMR_ERR_BADARG |
| 60 | |
| 61 | The message, or an internal portion of the message, was |
| 62 | corrupted or the pointer was invalid. |
| 63 | |
| 64 | |
| 65 | RMR_ERR_OVERFLOW |
| 66 | |
| 67 | The length passed in was larger than the maximum length of |
| 68 | the field; only a portion of the source bytes were copied. |
| 69 | |
