ILE C functions

 

ILE C provides the standard C functions defined by the American National Standards Institute (ANSI).

These functions can operate through either the data management I/O support or the integrated file system stream I/O support, depending on what you specify when you create the C program. The compiler uses the data management I/O unless you tell it differently.

To tell the compiler to use the integrated file system stream I/O, specify *IFSIO for the System interface option (SYSIFCOPT) parameter in the Create ILE C Module (CRTCMOD) or Create Bound C Program (CRTBNDC) command. When you specify *IFSIO, the integrated file system I/O functions are bound instead of the data management I/O functions. In effect, the C functions of ILE C use the integrated file system functions to perform I/O. Figure 1. ILE C functions use the integrated file system stream I/O functions

ILE C functions use the integrated file system stream I/O functions
