t_getstate() - get the current state SYNOPSIS
DESCRIPTION
The function returns the current state of the provider as seen by the application associated with the transport endpoint specified by fd. Fork Safety is not fork-safe. RETURN VALUE
State is returned upon successful completion. Otherwise, a value of -1 it returned and is set to indicate the error. The current state is one of the following: T_UNBND unbound T_IDLE idle T_OUTCON outgoing connection pending T_INCON incoming connection pending T_DATAXFER data transfer T_OUTREL outgoing orderly release (waiting for an orderly release indication). T_INREL incoming orderly release (waiting for an orderly release request). If the provider is undergoing a state transition when is called, the function will fail. ERRORS
On failure, is set to the following: [TBADF] The specified identifier does not refer to a transport endpoint. [TSTATECHNG] The transport provider is undergoing a transient state change. [TSYSERR] A system error has occurred during execution of this function. [TPROTO] (XTI only) This error indicates that a communication problem has been detected between XTI and the transport provider for which there is no suitable XTI ( SEE ALSO

t_getstate(3xti) t_getstate(3xti) Name t_getstate - get the current state Syntax #include <xti.h> int t_getstate(fd) int fd; Arguments fd Identifies the local transport endpoint the current state is returned from. Description The function returns the current state of the transport provider associated with the transport endpoint specified by fd. -------------------------------------- Parameters Before Call After Call -------------------------------------- fd x / -------------------------------------- Return Values Upon successful completion, returns the current state. On failure, a value of -1 is returned, and t_errno is set to indicate the error. The current state is one of the following: T_UNBND Unbound T_IDLE Idle T_OUTCON Outgoing connection pending T_INCON Incoming connection pending T_DATAXFER Data transfer T_OUTREL Outgoing orderly release (waiting for an orderly release indication) T_INREL Incoming orderly release (waiting to send an orderly release request) If the provider is undergoing a state transition when is called, the function fails. Diagnostics On failure, t_errno is set to one of the following: [TBADF] The specified file descriptor does not refer to a transport endpoint. This error may be returned when the fd has been previously closed or an erroneous number has been passed to the call. [TSTATECHNG] The transport provider is undergoing a transient state change. [TNOTSUPPORT] This function is not supported by the current implementation of XTI. [TSYSERR] A system error has occurred during execution of this function. See Also t_open(3xti) t_getstate(3xti)
