RETURN VALUES
For functions that return an integer, the return value is the specified
value on success and -1 on error.
The value of errno is not changed by these calls in the event of an
error.
ERRORS
These functions take a pointer to an integer error as an argument. If
the error is non-null, one of the following values is set:
EINVAL The input SIP message sip_msg or the header value is null; or
the specified header/header value is deleted.
EPROTO The header value is not present or invalid. The parser could
not parse it correctly.
ENOMEM There is an error allocating memory for the return value.
On success, the value of the location pointed to by error is set to 0.
