Control open file descriptors through the MIO library.
Modular I/O library (libmio.a)
#include <libmio.h>
int MIO_fcntl ( FileDescriptor, Command, Argument )
int FileDescriptor, Command, Argument;This subroutine is an entry point of the MIO library, offering the same features as the fcntl subroutine. Use this subroutine to instrument your application with the MIO library. You can replace the fcntl kernel I/O subroutine with this equivalent MIO subroutine. See Modular I/O in AIX® Version 7.1 Performance management for the MIO library implementation.
Use this subroutine to perform controlling operations on the open file specified by the FileDescriptor parameter. The FileDescriptor parameter results from the MIO_open64 subroutine.
The parameters are those of the corresponding standard POSIX system call fcntl.
The return values are those of the corresponding standard POSIX system call fcntl.
The error codes are those of the corresponding standard POSIX system call fcntl.
