remove-sigio-handler

Arguments: fd

This function is called for its side effects and its return value is not specified.

fd should be an integer identifying a Unix file descriptor. (We assume that the file descriptor has been established by a call to a Unix I/O operation such as open() and returned to Lisp via a call to a foreign function.)

Calling this function causes Unix to suppress issuing SIGIO signals on the Unix file descriptor identified by fd.

Sigio handlers are added by set-sigio-handler. See that page for an example.

Note that SIGIO handlers will only work if the sigio interface is available, as indicated by the return value of the function sigio-supported-p.
