C Reference Manual

The UNIX Programmer’s Manual [4] describes the library routines available to C programs under UNIX, and also the procedures for compiling programs under that system. ‘‘The GCOS C Library’’ by Lesk and Barres [5] describes routines available under that system as well as compilation procedures. Many of these routines, particularly the ones having to do with I/O, are also provided under UNIX. Finally, ‘‘Programming in C! A Tutorial,’’ by B. W. Kernighan [6], is as useful as promised by its title and the author’s previous introductions to allegedly impenetrable subjects.
