| @deftypefn Supplemental int snprintf (char *@var{buf}, size_t @var{n}, @ |
| const char *@var{format}, ...) |
| |
| This function is similar to @code{sprintf}, but it will write to |
| @var{buf} at most @code{@var{n}-1} bytes of text, followed by a |
| terminating null byte, for a total of @var{n} bytes. |
| On error the return value is -1, otherwise it returns the number of |
| bytes, not including the terminating null byte, that would have been |
| written had @var{n} been sufficiently large, regardless of the actual |
| value of @var{n}. Note some pre-C99 system libraries do not implement |
| this correctly so users cannot generally rely on the return value if |
| the system version of this function is used. |
