NAME

       select.h, select - select types

SYNOPSIS

       #include <sys/select.h>

DESCRIPTION

       The <sys/select.h> header defines the timeval structure, which includes the following members:

       time_t      tv_sec      /* seconds */
       suseconds_t tv_usec     /* microseconds */

       The time_t and suseconds_t types are defined as described in <sys/types.h>. See types.h(3HEAD).

       The sigset_t type is defined as described in signal.h(3HEAD).

       The timespec structure is defined as described in <time.h>. See time.h(3HEAD).

       The <sys/select.h> header defines the fd_set type as a structure.

       The following is defined as a macro:

       FD_SETSIZE      Maximum number of file descriptors in an fd_set structure.

       Inclusion of the <sys/select.h> header can make visible all symbols from the headers <signal.h>, <sys/time.h>, and <time.h>.
