sip_delete_start_line(3SIP)			   Session Initiation Protocol Library Functions		       sip_delete_start_line(3SIP)

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. ATTRIBUTES
