sip_get_msg_len(3SIP) Session Initiation Protocol Library Functions sip_get_msg_len(3SIP)NAME
sip_get_msg_len - returns the length of the SIP message
SYNOPSIS
cc [ flag ... ] file ... -lsip [ library ... ]
#include <sip.h>
int sip_get_msg_len(sip_msg_t sip_msg,
int *error);
DESCRIPTION
The sip_get_msg_len() function will return the length of the SIP message sip_msg.
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
This function takes 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.

sip_get_header(3SIP) Session Initiation Protocol Library Functions sip_get_header(3SIP)NAME
sip_get_header - get a SIP header from a message
SYNOPSIS
cc [ flag ... ] file ... -lsip [ library ... ]
#include <sip.h>
const struct sip_header *sip_get_header(sip_msg_t sip_msg,
char *header_name, sip_header_t old_header, int *error);
DESCRIPTION
The sip_get_header() function returns the header specified by header_name (long or compact form) from the SIP message sip_msg. If
header_name is NULL, the first header in the SIP message is returned. The old_header, if non-null, specifies the starting position in
sip_msg from which the search is started. Otherwise, the search begins at the start of the SIP message. For example, to get the first VIA
header from the SIP message sip_msg:
via_hdr = sip_get_header(sip_msg, "VIA", NULL, &error);
To get the next VIA header from sip_msg:
via_hdr = sip_get_header(sip_msg, "VIA", via_hdr, &error);
The sip_get_header() function ignores any header that is marked as deleted.
RETURN VALUES
On success, the sip_get_header() function returns the queried header. On failure, it returns NULL.
The value of errno is not changed by these calls in the event of an error.
ERRORS
The following value may be returned:
EINVAL The header_name specified in the SIP message is not present or has been deleted; or, the header_name is not specified and there
are no "un-deleted" headers in the SIP message.
