Description

The t_getstate function returns the current state of the transport provider associated with the transport endpoint specified by fd.

Return values

t_getstate returns the current state on successful completion and -1 on failure, and t_errno is set to indicate the error. The current state may be one of the following:

T_DATAXFER: data transfer
T_IDLE: idle
T_INCON: incoming connection pending
T_INREL: incoming orderly release (waiting for an orderly release request)
T_OUTCON: outgoing connection pending
T_OUTREL: outgoing orderly release (waiting for an orderly release indication)
T_UNBND: unbound

If the provider is undergoing a state transition when t_getstate is called, the function fails.

Diagnostics

On failure, t_errno may be set to one of the following:

[TBADF]: The specified file descriptor does not refer to a transport endpoint.
[TSTATECHNG]: The transport provider is undergoing a state change.
[TSYSERR]: A system error has occurred during execution of this function.
[TNOTSUPPORT]: This function is not supported by the current implementation of XTI.
