30       For functions that return an integer, the return value is the specified
31       value on success and -1 on error.
32
33
34       The  value  of  errno  is not changed by these calls in the event of an
35       error.
36

ERRORS

38       These functions take a pointer to an integer error as an  argument.  If
39       the error is non-null, one of the following values is set:
40
41       EINVAL    The input SIP message sip_msg or the header value is null; or
42                 the specified header/header value is deleted.
43
44
45       EPROTO    The header value is not present or invalid. The parser  could
46                 not parse it correctly.
47
48
49       ENOMEM    There is an error allocating memory for the return value.
50
51
52
53       On success, the value of the location pointed to by error is set to 0.
