Function Documentation

int FileRewind (  ClientData    clientData, Tcl_Interp *    interp, int    argc, char *    argv[] )  [static]

Callback for the Tcl FileRewind command. Rewinds the dump file. Parameters: clientData  Application global config info. interp  The Tcl interpreter handle. argc  The number of arguments. argv  Pointers to the argument strings. Returns: TCL_OK.

int LineAscii (  ClientData    clientData, Tcl_Interp *    interp, int    argc, char *    argv[] )  [static]

Callback for the Tcl LineAscii command. Expects: argv[1] = # of bytes to convert The ASCII version of the binary data is linked to the Tcl interpreter result field. Parameters: clientData  Application global config info. interp  The Tcl interpreter handle. argc  The number of arguments. argv  Pointers to the argument strings. Returns: TCL_OK.

int LineRead (  ClientData    clientData, Tcl_Interp *    interp, int    argc, char *    argv[] )  [static]

Callback for the Tcl LineRead command. Expects: argv[1] = # of bytes in data argv[2] = data format argv[3] = # of items to read The ASCII version of the binary data is linked to the Tcl interpreter result field. Parameters: clientData  Application global config info. interp  The Tcl interpreter handle. argc  The number of arguments. argv  Pointers to the argument strings. Return values: TCL_OK  Success. TCL_ERROR  Failure.

int main (  int    argc, char **    argv )

Application entry point. The program resources are intialized, then the Tcl and Tk interpreters are started using the script hd.tk". Parameters: argc  The number of command line arguments. argv  Pointer to the command line argument strings. Return values: 0  Success. -1  Failure.

int ReadFloat (  hd_config *    g, Tcl_Interp *    interp, int    size, int    numItems, char *    format )  [static]

Reads in one or more floating point values from the input file. The data is converted to the appropriate ASCII string and appended to the Tcl interpreter result field. Parameters: g  Application global config info. interp  The Tcl interpreter handle. size  The size in bytes of each item to read. numItems  The number of items to read and convert. format  The format string to apply. Return values: TCL_OK  Success. TCL_ERROR  Failure.

int ReadInteger (  hd_config *    g, Tcl_Interp *    interp, int    size, int    numItems, char *    format )  [static]

Reads in one or more integer values from the input file. The data is converted to the appropriate ASCII string and appended to the Tcl interpreter result field. Parameters: g  Application global config info. interp  The Tcl interpreter handle. size  The size in bytes of each item to read. numItems  The number of items to read and convert. format  The format string to apply. Return values: TCL_OK  Success. TCL_ERROR  Failure.

int Tcl_HdInit (  Tcl_Interp *    interp )  [static]

The Tcl/Tk initialization callback. This function is called by Tcl after the interpreter is created but before the application starts. The Tcl interpreter is expanded to handle the application specific commands. Parameters: interp  The Tcl interpreter handle. Return values: TCL_OK  Success. TCL_ERROR  Failure.
