Tt/tt_c.h(file formats)

NAME
Tt/tt_c.h — ToolTalk definitions

SYNOPSIS

#include &<Tt/tt_c.h>

DESCRIPTION

The Tt/tt_c.h header includes typedefs for the following callback functions:

typedef Tt_filter_action (*Tt_filter_function)(const char *nodeid,
        void *context,
        void *accumulator);

typedef Tt_callback_action (*Tt_message_callback)(Tt_message m,
        Tt_pattern p);

To enable developers to write multithreaded applications, the header defines

    typedef enum tt_feature {
        _TT_FEATURE_MULTITHREADED = 1,  // Thread-safety
        _TT_FEATURE_LAST                // Enum end marker
    } Tt_feature;

Note that the TT_FEATURE_MULTITHREADED value will be part of the libtt binary interface.

These would be accessed by calling code with corresponding #define constants:

#define TT_FEATURE_MULTITHREADED _TT_FEATURE_MULTITHREADED

in order that that calling code can then use cpp directives to control their use of features:

#if defined(TT_FEATURE_MULTITHREADED)
....
#endif

The header defines the TT_VERSION constant with the value 10200, indicating the version of the ToolTalk API.

The header defines the Tt_status enumeration data type, with the following members and specific values:

typedef enum tt_status {
        TT_OK                   = 0,

Specific values are required because they can be communicated between ToolTalk clients on different platforms, usually via tt_message_status_set(3) and tt_message_status(3).
