int fd, Pointer arg) #!EF #!N #!N Functional Details #!N #!N
Assigns a handler routine for input coming from an open file
descriptor. This function associates the routine #!F-adobe-times-bold-r-normal--18* proc #!EF with the
file descriptor #!F-adobe-times-bold-r-normal--18* fd #!EF and may be used to accept
input from a socket. When any input is available on #!F-adobe-times-bold-r-normal--18*
fd #!EF , the routine #!F-adobe-times-bold-r-normal--18* proc #!EF is called and
passed #!F-adobe-times-bold-r-normal--18* fd #!EF and #!F-adobe-times-bold-r-normal--18* arg #!EF . #!N #!N
The file descriptor is checked for input between module executions. Input
from #!F-adobe-times-bold-r-normal--18* fd #!EF does not interrupt modules; #!F-adobe-times-bold-r-normal--18* fd #!EF
is not checked for input before returning from DXRegisterInputHandler. #!N #!N
Calling DXRegisterInputHandler with #!F-adobe-times-bold-r-normal--18* proc=NULL #!EF unregisters the handler. #!N #!N
Return Value #!N #!N Returns #!F-adobe-times-bold-r-normal--18* OK #!EF , or returns
#!F-adobe-times-bold-r-normal--18* ERROR #!EF and sets the error code to indicate an
error. #!N #!N See Also #!N #!N #!F-adobe-times-bold-r-normal--18* #!Ldxrtr,dxall1351 h DXReadyToRun #!EL #!EF #!N
