DESCRIPTION
|
|
|
|
Reads at most <[n-1]> characters from <[fp]> until a newline
|
|
|
|
is found. The characters including to the newline are stored
|
|
|
|
in <[buf]>. The buffer is terminated with a 0.

|
<<fgets_unlocked>> is a non-thread-safe version of <<fgets>>.
|
|
|
|
<<fgets_unlocked>> may only safely be used within a scope
|
|
|
|
protected by flockfile() (or ftrylockfile()) and funlockfile(). This
|
|
|
|
function may safely be used in a multi-threaded program if and only
|
|
|
|
if they are called while the invoking thread owns the (FILE *)
|
|
|
|
object, as is the case after a successful call to the flockfile() or
|
|
|
|
ftrylockfile() functions. If threads are disabled, then
|
|
|
|
<<fgets_unlocked>> is equivalent to <<fgets>>.
|
|
|
|
|
|
|
|
The functions <<_fgets_r>> and <<_fgets_unlocked_r>> are simply
|
|
|
|
reentrant versions that are passed the additional reentrant structure
|
|
|
|
pointer argument: <[ptr]>.
|
2000-02-18 03:39:52 +08:00
|
|
|
|
|
|
|
RETURNS
|
|
|
|
<<fgets>> returns the buffer passed to it, with the data
|
|
|
|
filled in. If end of file occurs with some data already
|
|
|
|
accumulated, the data is returned with no other indication. If
|
|
|
|
no data are read, NULL is returned instead.
|
|
|
|
|
|
|
|
PORTABILITY
|
|
|
|
<<fgets>> should replace all uses of <<gets>>. Note however
|
|
|
|
that <<fgets>> returns all of the data, while <<gets>> removes
|
|
|
|
the trailing newline (with no indication that it has done so.)
