The ''mac_addr'' parameter should be a 6 byte buffer containing a MAC address for mac2string, or 6 bytes of storage to receive the converted address for string2mac. The ''mac_string'' argument must be at least 19 bytes long to receive an 18 character null terminated string.<br /> <br /> The '''string2mac()''' function takes, as valid input, a MAC address string as pairs of hexadecimal numbers separated by colons, as in the following example:<br /> <br /> 00:55:AA:12:7C:9E<br /> <br /> The '''mac2string()''' function returns the string representation of the 6 byte MAC address in this format. The routine is case sensitive; letters forming a hex number must be in upper case.<br /> <br /> == Return values ==<br /> <br /> The '''string2mac()''' C function returns 0 on success, or -1 if it can't parse the supplied string. The assembly language interface returns with carry reset on success, or carry set on error.<br /> <br /> [[Category:Spectranet]]</div>
