sia_timed_action(3) Library Functions Manual sia_timed_action(3) NAME
sia_timed_action - Time limit routine - SIA (Security Integration Architecture) LIBRARY
Standard C library (libc.so and libc.a) SYNOPSIS
#include <siad.h> int sia_timed_action( int *(action)(), void *params, time_t timeout); 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. FILES

sia_chdir(3) Library Functions Manual sia_chdir(3) NAME
sia_chdir - Interface to the chdir system call - SIA (Security Integration Architecture) LIBRARY
Standard C library (libc.so and libc.a) SYNOPSIS
#include <siad.h> int sia_chdir( const char * directory, time_t timelimit); PARAMETERS
directory The specified new working directory. The parameter must be an ASCII string. If it is a NULL, SIAFAIL is returned. timelimit The number of seconds to allow for the chdir call. If a 0 is specified, there is no timeout. If the value is less than 0, SIA_DEF_TIMEOUT is used. DESCRIPTION
The sia_chdir() routine implements a "NFS-safe" way to change the current working directory. This routine calls the chdir() system call which is protected by alarm() and signal-handling for SIGALRM, SIGHUP, SIGINT, SIGQUIT, and SIGTERM. Receipt of any of these signals causes the chdir() operation to fail. If the chdir call completes within the time limit given, the call succeeds. RETURN VALUES
The sia_chdir() routine returns SIASUCCESS or SIAFAIL. 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. FILES
