INET_NTOP(3) Linux Programmer's Manual INET_NTOP(3)NAMEinet_ntop - convert IPv4 and IPv6 addresses from binary to text formSYNOPSIS#include <arpa/inet.h> const char *inet_ntop(int af, const void *src, char *dst, socklen_t size);DESCRIPTIONThis function converts the network address structure src in the af address family into a character string. The resulting string is copied to the buffer pointed to by dst, which must be a non-NULL pointer. The caller specifies the number of bytes available in this buffer in the argument size. inet_ntop() extends the inet_ntoa(3) function to support multiple address families, inet_ntoa(3) is now considered to be deprecated in favor of inet_ntop(). The following address families are currently supported: AF_INET src points to a struct in_addr (in network byte order) which is converted to an IPv4 network address in the dotted-decimal format, "ddd.ddd.ddd.ddd". The buffer dst must be at least INET_ADDRSTRLEN bytes long. AF_INET6 src points to a struct in6_addr (in network byte order) which is converted to a representation of this address in the most appropri- ate IPv6 network address format for this address. The buffer dst must be at least INET6_ADDRSTRLEN bytes long.RETURN VALUEOn success, inet_ntop() returns a non-NULL pointer to dst. NULL is returned if there was an error, with errno set to indicate the error.ERRORSEAFNOSUPPORT af was not a valid address family. ENOSPC The converted address string would exceed the size given by size.CONFORMING TOPOSIX.1-2001. Note that RFC 2553 defines a prototype where the last argument size is of type size_t. Many systems follow RFC 2553. Glibc 2.0 and 2.1 have size_t, but 2.2 and later have socklen_t.BUGSAF_INET6 converts IPv4-mapped IPv6 addresses into an IPv6 format.EXAMPLESee inet_pton(3).SEE ALSOgetnameinfo(3), inet(3), inet_pton(3)COLOPHONThis page is part of release 3.53 of the Linux man-pages project.
