tt_session_prop(3)

NAME
     tt_session_prop - return the ith value of a session property

SYNOPSIS
     #include <Tt/tt_c.h>
     char *tt_session_prop(const char *sessid,
                           const char *propname,
                           int i);

DESCRIPTION
     The tt_session_prop() function returns the ith value of the specified
     session property.

     The sessid argument is the name of the session joined.  The application
     can use the sessid value returned when tt_default_session() is called.
     The propname argument is the name of the property from which a value is
     to be retrieved.  The name must be less than 64 bytes.  The i argument is
     the number of the item in the property name list for which the value is
     to be obtained.  The list numbering begins with zero.

RETURN VALUE
     Upon successful completion, the tt_session_prop() function returns the
     value of the requested property.  If there are i values or fewer, it
     returns NULL.  The application can use tt_ptr_error(3) to extract one of
     the following Tt_status values from the returned pointer:

        TT_OK   The operation completed successfully.

        TT_ERR_NOMP
                The ttsession(1) process is not running and the ToolTalk
                service cannot restart it.

        TT_ERR_NUM
                The integer value passed was invalid (out of range).

        TT_ERR_PROPNAME
                The specified property name is syntactically invalid.

        TT_ERR_SESSION
                The specified ToolTalk session is out of date or invalid.

APPLICATION USAGE
     The application should use tt_free(3) to free any data stored in the
     address returned by the ToolTalk API.

     If the returned value has embedded nulls, it is impossible to determine
     how long it is.  The application can use tt_session_bprop(3) for values
     with embedded nulls.
