NAME

isetlockwait, igetlockwait − will set/return the current state of the lockwait flag

SYNOPSIS

#include <sicl.h>

int isetlockwait(INST id, int flag);

int igetlockwait(INST id, int flag);

DESCRIPTION

isetlockwait controls whether a call to ilock will cause a hang or generate an error if the device is locked by another user.  If flag is non-zero, then all operations to a device/interface locked by another user will hang (wait) for the lock to be freed (default).  If flag is (0), the operation will return an error. 

getlockwait will store a (1) into flag if hang (wait) mode is enabled, and will store a (0) if no-wait (generate error) mode is enabled. 

RETURN VALUE

isetlockwait, and igetlockwait return a (0) on success, or a non-zero error code if an error was encountered. 

ERRORS

isetlockwait, igetlockwait fail under the following circumstances, and sets the return value to one of the following values:
 

­[I_ERR_NORSRC] Out of system resources

­[I_ERR_NOINTF] Interface is not active

­[I_ERR_NODEV] Device is not active

­[I_ERR_BADID] The INST id is invalid
