NAME

       sip_delete_start_line, sip_delete_header, sip_delete_header_by_name, sip_delete_value - delete a SIP header or a header value

SYNOPSIS

       cc [ flag ... ] file ... -lsip [ library ... ]
       #include <sip.h>

       int sip_delete_start_line(sip_msg_t sip_msg);

       int sip_delete_header(sip_msg_t sip_header);

       int sip_delete_header_by_name(sip_msg_t msg,
	    char *header_name);

       int sip_delete_value(sip_header_t sip_header,
	    sip_header_value_t sip_header_value);

DESCRIPTION

       The sip_delete_start_line() function deletes the start line, a request or a response line, from the SIP message sip_msg.

       The sip_delete_header() function deletes the SIP header specified by sip_header from the associated SIP message sip_msg.

       The  sip_delete_header_by_name()  function deletes the SIP header name specified by header_name (long or compact form) from the SIP message
       sip_msg.

       The sip_delete_value() deletes the SIP header value specified by sip_header_value from the SIP header sip_header.

       When a SIP header or value is deleted, the corresponding header or value is marked as deleted.  Lookups ignore headers or values  that  are
       marked as deleted.

RETURN VALUES

       These functions return 0 on success and the appropriate error on failure.

       The value of errno is not changed by these calls in the event of an error.

ERRORS

       On failure, the returned error could be one of the following:

       EINVAL	 If any of the required input is NULL.

		 If the header or value to be deleted does not exist.

		 If the header or value to be deleted has already been deleted.

       EPERM	 If the SIP message cannot be modified.

NAME

       sip_copy_start_line, sip_copy_header, sip_copy_header_by_name, sip_copy_all_headers - copy headers from a SIP message

SYNOPSIS

       cc [ flag ... ] file ... -lsip [ library ... ]
       #include <sip.h>

       int sip_copy_start_line(sip_msg_t from_msg, sip_msg_t to_msg);

       int sip_copy_header(sip_msg_t sip_msg, sip_header_t sip_header,
	    char *param);

       int sip_copy_header_by_name(sip_msg_t from_msg, sip_msg_t to_msg,
	    char *header_name, char *param);

       int sip_copy_all_headers(sip_msg_t from_msg, sip_msg_t to_msg);

DESCRIPTION

       The sip_copy_start_line() function copies the start line, a request or a response line, from from_msg to to_msg.

       The  sip_copy_header()  function copies the SIP header specified by sip_header to the SIP message sip_msg. A new SIP header is created from
       sip_header and param, and is appended to sip_msg. The param can be non-null.

       The sip_copy_header_by_name() function copies the header specified by header_name (long or short form) from from_msg  to  to_msg.  The  new
       header is created using the header value from from_msg and param, if non-null, and appended to to_msg.

       The sip_copy_all_headers() copies all the headers from from_msg to to_msg.

RETURN VALUES

       These functions return 0 on success and the appropriate error on failure.

       The value of errno is not changed by these calls in the event of an error.

ERRORS

       These functions can return one of the following errors in case of failure:

       EINVAL	 If the required input parameters are NULL or if the header being copied does not exist or is deleted in source SIP message.

       ENOMEM	 Error while allocating memory for creating the new header.

       EPERM	 If the input SIP message cannot be modified.
