publib is a library of C functions that are useful in many of programs. It is an extension to the
Standard C library (as defined by the ISO/ANSI C standard 9899-1990). To use the functions in publib,
#include <publib.h> and link with the libpub.a library (adding -lpub at the end of the link command
should work, if the library has been installed properly).
The library provides functions for
string and memory area manipulation
memory allocation
I/O
comparison functions for qsort, bsearch, and others
expression evaluation
