33 int rmr_bytes2xact( rmr_mbuf_t* mbuf, unsigned char* src, int len )
40 The ``rmr_bytes2xact`` function will copy up to *len* bytes
41 from *src* to the transaction ID (xaction) field in the
42 message. The field is a fixed length, gated by the constant
43 ``RMR_MAX_XID`` and if len is larger than this value, only
44 ``RMR_MAX_XID`` bytes will actually be copied.
50 On success, the actual number of bytes copied is returned, or
51 -1 to indicate a hard error. If the length is less than 0, or
52 not the same as length passed in, ``errno`` is set to one of
53 the errors described in the *Errors* section.
59 If the returned length does not match the length passed in,
60 ``errno`` will be set to one of the following constants with
61 the meaning listed below.
70 The message, or an internal portion of the message, was
71 corrupted or the pointer was invalid.
75 The length passed in was larger than the maximum length of
76 the field; only a portion of the source bytes were copied.
