io_trywritetimeout(3) - Linux man page
Name
io_trywritetimeout - write to a descriptor without blockingSyntax
#include <io.h>int io_trywritetimeout(int64 fd,const char* buf,int64 len);
Description
io_trywritetimeout is identical to io_trywrite, with the following exception: if
- [bu]
- io_trywrite returns -1 (the descriptor is not ready for writing), and
- [bu]
- the descriptor has a timeout, and
- [bu]
- the write attempt was after the descriptor's timeout,
then io_trywritetimeout instead returns -2, with errno set to ETIMEDOUT.
