This section alphabetically lists the screen functions from the screen.h file and describes their purpose, syntax, parameters, and return values. These functions have been divided into the following groups:
The standard ANSI functions, such as getchar and putchar, can also be used. See ANSI File and Directory Functions.
To facilitate the porting of CLib applications, LibC supports the NWSNUT functions and includes a modified nwsnut.h file. For more information about these screen handling functions, see NDK: NLM User Interface Developer Components.
IMPORTANT:If you use functions from event.h and from nwsnut.h, the severity flags in nwsnut.h are redefined so that they do not conflict with the alertSeverity definitions in event.h. Your nwsnut code will need to be modified to use these new defines.
For an overview of the types of screen functions available in LibC and the methods available for creating a screen, see Section 3.3, Screen Management.
