NAME¶
ndelay_off - put file descriptor in non-blocking mode
SYNTAX¶
#include <ndelay.h>
extern int
ndelay_off(int
fd);
DESCRIPTION¶
ndelay_off puts a file descriptor in blocking mode. Reading from and writing to
blocking network sockets, FIFOs or device files will possibly not return
immediately but wait on more input or buffer space for output.
If an error occurred, ndelay_off will return nonzero and set
errno
accordingly.
