The section of the SunOS Reference Manual that describes the C library functions (but does not include the system calls) now contains six books instead of one. These books are:
Library Interfaces and Headers
Basic Library Functions
Networking Library Functions
Threads and Realtime Library Functions
Extended Library Functions
Curses Library Functions
In addition, many of the man page suffixes have been changed to reflect the library that contains the function (for example, all man pages describing functions contained in libnsl now have the suffix .3nsl).
