NAME

sia_timed_action − Time limit routine - SIA (Security Integration Architecture)

SYNOPSIS

#include <siad.h>
int sia_timed_action(
        int ∗(action)(),
        void  ∗params,
        time_t timeout );

LIBRARY

Standard C library (libc.so and libc.a)

PARAMETERS

action()
This parameter is a function pointer to the action being timed. 

params
The parameters to the function specified with the action() parameter. 

timeout
The maximum time in seconds allowed for the action.

DESCRIPTION

The sia_timed_action() routine provides a way to call a function with a time limit and signal protection. If SIGHUP, SIGINT, SIGQUIT, SIGTERM, or SIGALRM is received, sia_timed_action() fails. 

RETURN VALUES

The sia_timed_action() routine returns SIAFAIL if a SIGHUP, SIGINT, SIGQUIT, SIGTERM, or SIGALRM signal is received or if a timeout occurs. Otherwise, the return value from the action() call is returned. 

ERRORS

The errno value is not (normally) set explicitly by sia_∗ routines. The errno values are those returned from the dynamic loader interface, from dependent (siad_∗) routines, or from malloc. Possible errors include resource constraints (no memory) and various authentication failures.
