In particular, it describes the functions of two C language libraries: the standard C library, and the screen updating and cursor movement library cur'eI. The C library functions may be called by any program that needs the resources of the XENIX system to perform a task. The functions let programs read and write to files in the XENIX file system, read and write to devices such as terminals and lineprinters, load and execute other programs, receive a.nd process signals, communicate with other programs through pipes, share system resources, a.nd process errors. 1.2 Using the C Library Functions To use the C library functions you must include the proper function call and definitions in the program and specify the corresponding library is given when the program is compiled. The standard C libra.ry, contained in the file libe./I, is automatically specified when you compile a C language program. Other libraries, including the screen updating and cursor movement library contained in the file libcur,e
