|
|
---------------------------------------------
|
|
ssize_t send(int fd, const void* buf, size_t n, int flags);
|
|
---------------------------------------------
|
|
|
|
Sends `n` bytes from the buffer `buf` over the socket `fd`. Returns the number of bytes sent, or
|
|
the negation of the error code on error. It is possible for the number of bytes sent to be smaller than the number
|
|
of bytes requested.
|
|
|
|
IMPORTANT: If the system call is interrupted, this function will return `-EINTR`. This differs from most C runtimes,
|
|
where `-1` is returned with `errno` set to `EINTR`. As this runtime does not have `errno`, callers should check
|
|
for `-EINTR` and a result less than zero in the error checking code.
