Windows:使用CoCreateGuid函数(GUID)
- #include <objbase.h>
- #include <stdio.h>
- #define GUID_LEN 64
- int main(int argc, char* argv[])
- {
- char buffer[GUID_LEN] = { 0 };
- GUID guid;
- if ( CoCreateGuid(&guid) )
- {
- fprintf(stderr, "create guid error\n");
- return -1;
- }
- _snprintf(buffer, sizeof(buffer),
- "%08X-%04X-%04x-%02X%02X-%02X%02X%02X%02X%02X%02X",
- guid.Data1, guid.Data2, guid.Data3,
- guid.Data4[0], guid.Data4[1], guid.Data4[2],
- guid.Data4[3], guid.Data4[4], guid.Data4[5],
- guid.Data4[6], guid.Data4[7]);
- printf("guid: %s\n", buffer);
- return 0;
- }
Linux:使用uuid_generate函数(UUID)
- //编译命令:gcc atemp.c -o atemp -luuid
- #include <stdio.h>
- #include <uuid/uuid.h>
- int main()
- {
- uuid_t uu;
- int i;
- uuid_generate( uu );
- for(i=0;i<16;i++)
- {
- printf("%02X-",uu[i]);
- }
- printf("\n");
- return 0;
- }
