char bgets(char buffer, size_t count, FILE stream,
const char breakstring);
bgets reads characters from stream into buffer
until either count is exhausted or one of the characters in
breakstring is encountered in the stream.
The read data is terminated with a null byte ('\0')
and a pointer to the trailing null is returned.
If a breakstring character is encountered, the last non-null
is the delimiter character that terminated the scan.
Note that, except for the fact that the returned value points to the
end of the read string rather than to the beginning, the call
bgets(buffer, sizeof buffer, stream, "\n");
is identical to
fgets(buffer, sizeof buffer, stream);
There is always enough room reserved in the buffer for the trailing
If breakstring is a null pointer, the value of breakstring
from the previous call is used.
If breakstring is null at the first call, no characters will be
used to delimit the string.
NULL is returned on error or end-of-file.
Reporting the condition is delayed to the next
call if any characters were read but not yet returned.
