IP address handling

Data Structures | |
| struct | ip_addr |
| A union struct for both IP version's addresses. More... | |
Modules | |

Typedefs | |
| typedef struct ip_addr | ip_addr_t |
| A union struct for both IP version's addresses. | |
Enumerations | |
| enum | lwip_ip_addr_type { IPADDR_TYPE_V4 = 0U, IPADDR_TYPE_V6 = 6U, IPADDR_TYPE_ANY = 46U } |

Functions | |
| char * | ipaddr_ntoa (const ip_addr_t *addr) |
| Convert numeric IP address (both versions) into ASCII representation. | |
| char * | ipaddr_ntoa_r (const ip_addr_t *addr, char *buf, int buflen) |
| Same as ipaddr_ntoa, but reentrant since a user-supplied buffer is used. | |
| int | ipaddr_aton (const char *cp, ip_addr_t *addr) |
| Convert IP address string (both versions) to numeric. | |

Function Documentation
| int ipaddr_aton | ( | const char * | cp, |
| ip_addr_t * | addr | ||
| ) |
| char* ipaddr_ntoa | ( | const ip_addr_t * | addr ) |
Convert numeric IP address (both versions) into ASCII representation.
returns ptr to static buffer; not reentrant!
- Parameters:
-
addr ip address in network order to convert
- Returns:
- pointer to a global static (!) buffer that holds the ASCII representation of addr
| char* ipaddr_ntoa_r | ( | const ip_addr_t * | addr, |
| char * | buf, | ||
| int | buflen | ||
| ) |
Same as ipaddr_ntoa, but reentrant since a user-supplied buffer is used.
- Parameters:
-
addr ip address in network order to convert buf target buffer where the string is stored buflen length of buf
- Returns:
- either pointer to buf which now holds the ASCII representation of addr or NULL if buf was too small
