my version of strlcpy
- by robUK
Hello,
gcc 4.4.4 c89
My program does a lot of string coping. I don't want to use the strncpy as it doesn't nul terminate. And I can't use strlcpy as its not portable.
Just a few questions. How can I put my function those its paces to ensure that it is completely safe and stable. Unit testing?
Is this good enough for production?
size_t s_strlcpy(char *dest, const char *src, const size_t len)
{
size_t i = 0;
/* Always copy 1 less then the destination to make room for the nul */
for(i = 0; i < len - 1; i++)
{
/* only copy up to the first nul is reached */
if(*src != '\0') {
*dest++ = *src++;
}
else {
break;
}
}
/* nul terminate the string */
*dest = '\0';
/* Return the number of bytes copied */
return i;
}
Many thanks for any suggestions,
