NAME
getipsecprotobyname, getipsecprotobynum - query IPsec protocols entries SYNOPSIS
cc -flag ... file ...-lnsl [-library ...] #include <netdb.h> int getipsecprotobyname(const char *proto_name); char *getipsecprotobynum(int proto_num); DESCRIPTION
Use the getipsecprotobyname() and getipsecprotobynum() functions to obtain the IPsec algorithm mappings that are defined by ipsecalgs(1M). You can also use the getipsecprotobyname() and getipsecprotobynum() functions in conjunction with getipsecalgbyname(3NSL) and getipsecal- gbynum(3NSL) to obtain information about the supported IPsec algorithms. The IPsec algorithms and associated protocol name spaces are defined by RFC 2407. getipsecprotobyname() takes as an argument the name of an IPsec protocol and returns its assigned protocol number. The character string returned by the getipsecprotobyname() function must be freed by the called when it is no longer needed. getipsecprotobynum() takes as an argument a protocol number and returns the corresponding protocol name. The following protocol numbers are pre-defined: IPSEC_PROTO_ESP Defines the encryption algorithms (transforms) that can be used by IPsec to provide data confidentiality. IPSEC_PROTO_AH Defines the authentication algorithms (transforms) that can be used by IPsec to provide authentication. PARAMETERS
proto_name A pointer to the name of an IPsec protocol. proto_num A pointer to a protocol number. conditions. RETURN VALUES
The getipsecprotobyname() function returns a protocol number upon success, or -1 if the protocol specified does not exist. The getipsecprotobynum() function returns a protocol name upon success, or the NULL value if the protocol number specified does not exist. ATTRIBUTES
