System Functions (s and S) spt_getcharx(2)

[EINTR] The read operation was interrupted by a signal that was caught, and no data was

transferred.

[ENXIO] A request was made on a nonexistent device, or the request was outside the

capabilities of the device.

[EIO] The call is attempting to read from the process’s controlling terminal and either

the process is ignoring or blocking the SIGTTIN signal or the process group is

orphaned.

[ENOMEM] Insufﬁcient memory is available for the operation.

Any error encountered during the underlying call to the spt_readx() function can cause this

function to return the corresponding errno value reported by the spt_readx() function. If your

application program encounters an errno value not listed on this reference page, see the

spt_readx(2) reference page either online or in the Open System Services System Calls Refer-

ence Manual for information about the cause of that error.
