net_aton(3C) net_aton(3C)NAMEnet_aton(), net_ntoa() - network station address string conversion routinesSYNOPSISDESCRIPTIONand translate station addresses between hexadecimal, octal or decimal, and binary formats: converts a hexadecimal, octal, or decimal address to a binary address. converts a binary address to an ASCII hexadecimal address. Both routines are provided in the standard C library and are loaded automatically during compilation. net_aton Parameters The following parameters are used by dstr Pointer to the binary address returned by the function. sstr Pointer to a null-terminated ASCII form of a station address (Ethernet or IEEE 802.3). This address can be an octal, dec- imal, or hexadecimal number as used in the C language (in other words, a leading 0x or 0X implies hexadecimal; a leading 0 implies octal; otherwise, the number is interpreted as decimal). size Length of the binary address to be returned in dstr. The length is 6 for Ethernet/IEEE 802.3 addresses. net_ntoa Parameters converts a 48-bit binary station address to its ASCII hexadecimal equivalent. The following parameters are used by dstr Pointer to the ASCII hexadecimal address returned by the function. dstr is null-terminated and padded with leading zeroes if necessary. dstr must be at least (2 x size + 3) bytes long to accommodate the size of the converted address. sstr Pointer to a station address in its binary form. size Length of sstr.RETURN VALUEand return NULL if any error occurs.EXAMPLES#include <netio.h> #define destination_addr "0x00DD0002AD00" ... struct fis arg; char str[16]; ...
