TIMEOUT_FDOPEN(3) Library Functions Manual TIMEOUT_FDOPEN(3) NAME timeout_fdopen -- I/O streams with timeouts LIBRARY PDEL Library (libpdel, -lpdel) SYNOPSIS #include <sys/types.h> #include <stdio.h> #include <pdel/io/timeout_fp.h> FILE * timeout_fdopen(int fd, const char *mode, int timeout); DESCRIPTION timeout_fdopen() is equivalent to fdopen(3) with the addition of an en- forced timeout on read or write operations on the underlying file descrip- tor fd. If any read or write operation blocks for longer than timeout seconds, an error is returned with errno set to ETIMEDOUT. If timeout is zero or negative, no timeout is imposed and the behavior is identical to fdopen(3). fclose(3) should be used to close the returned stream. RETURN VALUES timeout_fdopen() returns NULL to indicate an error, with errno set appro- priately.
