This newsgroup is read by a lot of programmers with varying degrees of skill. The more become aware of strncpy's woes, the less likely they will be producing buggy code using it.


For the edification a programmer (myself) with varying degrees of skill, what exactly are strncpy's "woes?"

/*
Evil, buggy code. Don't do this at home kids.
*/

char buff[32];

strncpy(buff, argv[1], 32);
printf("Your string was %s\n", buff);

/*
This is just as bad in its way, but not an error
*/
char buff[1024];

char *bottleneck = "a string in an inner loop";

strncpy(buff, bottleneck, 1023);
buff[1023] = 0;
