sip_get_param_value(3SIP) Session Initiation Protocol Library Functions sip_get_param_value(3SIP) NAME
sip_get_param_value, sip_get_params, sip_is_param_present - get parameter information for a SIP header value SYNOPSIS
cc [ flag ... ] file ... -lsip [ library ... ] #include <sip.h> const sip_str_t *sip_get_param_value (sip_header_value_t header_value, char *param_name, int *error); const sip_param_t *sip_get_params (sip_header_value_t header_value, int *error);; boolean_t sip_is_param_present (const sip_param_t *param_list, char *param_name, int param_len); DESCRIPTION
The sip_get_param_value() function returns the value for the parameter name specified by param_name from the SIP header value header_value. For functions that return a pointer of type sip_str_t, sip_str_t is supplied by: typedef struct sip_str { char *sip_str_ptr; int sip_str_len; }sip_str_t; The sip_str_ptr parameter points to the start of the returned value and sip_str_len supplies the length of the returned value. The sip_get_params() function returns the parameter list, if any, for the SIP header value header_value. The sip_is_param_present() function returns B_TRUE if the parameter specified by param_name of length supplied in param_len is present in the parameter list, param_list. Otherwise, it returns B_FALSE. RETURN VALUES
With the exception of sip_is_param_present(), these functions return the queried value on success and NULL on failure. The value of errno is not changed by these calls in the event of an error. ERRORS
If the error is non-null, one of the following values is set: EINVAL If any of the required input is NULL or if the specified SIP header value is marked deleted. EPROTO If the returned SIP header value is invalid (i.e. the parser encountered errors when parsing the value). On success, the value of the location pointed to by error is set to 0. ATTRIBUTES

sip_get_request_method(3SIP) Session Initiation Protocol Library Functions sip_get_request_method(3SIP) NAME
sip_get_request_method, sip_get_response_code, sip_get_response_phrase, sip_get_sip_version - obtain attributes from the start line in a SIP message SYNOPSIS
cc [ flag ... ] file ... -lsip [ library ... ] #include <sip.h> sip_method_t sip_get_request_method(const sip_msg_t sip_msg, int *error); int sip_get_response_code(sip_msg_t sip_msg, int *error); const sip_str_t *sip_get_response_phrase(sip_msg_t sip_msg, int *error); const sip_str_t*sip_get_sip_version(sip_msg_t sip_msg, int *error); DESCRIPTION
For functions that return a pointer of type sip_str_t, sip_str_t is supplied by: typedef struct sip_str { char *sip_str_ptr; int sip_str_len; }sip_str_t; The sip_str_ptr parameter points to the start of the returned value and sip_str_len supplies the length of the returned value. For example, given the following request line in a SIP message sip_msg that is input to sip_get_request_uri_str(): FROM : <Alice sip:alice@atlanta.com>;tag=1928301774 the return is a pointer to sip_str_t with the sip_str_ptr member pointing to "A" of Alice and sip_str_len being set to 5, the length of Alice. Access functions for headers that can have multiple values take the value as the input, while those that can have only one value take the SIP message sip_msg as the input. The sip_get_request_method() function will return the SIP method from the request line in the SIP message sip_msg. The method can be one of the following: INVITE ACK OPTIONS BYE CANCEL REGISTER REFER INFO SUBSCRIBE NOTIFY PRACK UNKNOWN The sip_get_response_code() function will return the response code response from the request line in the SIP message sip_msg. The sip_get_respose_phrase() function will return the response phrase response from the request line in the SIP message sip_msg. The sip_get_sip_version() function will return the version of the SIP protocol from the request or the response line in the SIP message sip_msg. RETURN VALUES
For functions that return a pointer to sip_str_t, the return value is the specified value on success or NULL in case of error. For func- tions 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. ATTRIBUTES
