NAME

       stLog, stQuietFlag, stShutupFlag, stProgramName, stMessage, stGetFromStdin, stAskConfirm, stGetTermWidth - user interaction

SYNOPSIS

       #include <config.h>
       #include <sttk.h.h>

       voidstLog (char *logMsg, int logType);

       int stQuietFlag;

       int stShutupFlag;

       char*stProgramName;

       charstMessage[];

       char*stGetFromStdin (int termChar);

       int stAskConfirm (char *message, char *defaultAnswer);

       int stGetTermWidth (int fdes);

DESCRIPTION

       These functions do the dialogue with the user. stLog outputs a message to the user's terminal. The message text is given in the logMsg buf-
       fer. logType is one of

       ST_LOG_MSG    Message to be sent to standard output.

       ST_LOG_MSGERR
		     Message to be sent to standard error.

       ST_LOG_WARNING
		     Warning message, preceded by the string `programName - warning:', going to standard error.

       ST_LOG_ERROR  Error message, preceded by the string `programName - error:', going to standard error.

       Additionally, when the flag

       ST_LOG_NONL   is ored to the message type (e.g. `ST_LOG_MSG | ST_LOG_NONL'), the message is printed without  adding  a  newline	character.
		     Otherwise, a newline is always added.

       Whether	a  message  really makes it's way to the user, depends on the variables stQuietFlag and stShutupFlag. When stQuietFlag is set to a
       non null value, all messages except error messages (ST_LOG_ERROR) will be suppressed. With the stShutupFlag set to a null value,  all  mes-
       sages will be suppressed. Initially, both flags are set to NULL.

       The  stProgramName  pointer  should  be	set  pointing to a buffer containing the name how the program was called. It is used for composing
       proper error messages and warnings (see above).

       stMessage is a buffer for constructing messages using sprintf(3). It is designed to be large enough to hold a file's pathname and an  addi-
       tional short message. It's size is MAXPATHLEN+128.

       stGetFromStdin  reads  from  stdin a text terminated by ^D or by the specified single character termChar at the beginning of a new line. If
       termChar is -1 text is terminated by ^D.

       stAskConfirm returns true if the answer is equivalent to defaultAnswer (assumption).

       stGetTermWidth returns the actual with of the user's termainal in columns.

BUGS

       stGetTermWidth will not work on all machines properly. In it's current implementation, it is quite SUN specific.
