ftn/getc(3) -- get a character from a logical unit
|
|
These routines return the next character from a file associated with a fortran logical unit, bypassing normal fortran I/O. Getc reads from logical unit 5, normally connected to the control terminal input. The value of each function is a system status code. Zero indicates no error occurred on the read; -1 indicates end of file was detected. A positive value will be either a UNIX system error code or an f77 I/O error code. See perror(3F).... |

getc(3s) -- get character or word from a stream
|
|
Fgetc and getc return the next character (if it exists) from the named input stream, as an unsigned character converted to an integer. It also moves the file pointer, if defined, ahead one character in stream. getchar is defined as getc(stdin). Each of getc,getchar and fgetc exist as functions in the C library. Getc and getchar are also available as macros in (see below under CAVEATS for important details on the implementation of these macros.) Getw returns the next word (i.e., integer... |

Tcl_Interp *interp (in) Interpreter to use for error reporting. Tk_Window tkwin (in) Token for window in which colormap will be used. char *string (in) Selects a colormap: either new or the name of a window with the same screen and visual as tkwin. Display *display (in) Display for which colormap was allocated. Colormap colormap (in) Colormap to free; must have been returned by a previous call to Tk_GetColormap or Tk_GetVisual.... |

standard/getcmmode(3) -- returns the current color map mode
|
|
none FUNCTION RETURN VALUE There are two possible returned values for this function: TRUE indicates that onemap mode is active. FALSE indicates that multimap mode is active. |

XColor *prefPtr (in) Indicates red, green, and blue intensities of desired color. XColor *colorPtr (in) Pointer to X color information. Must have been allocated by previous call to Tk_GetColor or Tk_GetColorByValue, except when passed to Tk_NameOfColor. Drawable drawable (in) Drawable in which the result graphi... |
|
standard/getcpos(3) -- returns the current character position
|
|
ix expects the pointer to the location at which to write the x coordinate of the current character position. iy expects the pointer to the location at which to write the y coordinate of the current character position. |
|
standard/getcursor(3) -- maintain database of cursors
|
|
Tcl_Interp *interp (in) Interpreter to use for error reporting. Tk_Window tkwin (in) Token for window in which the cursor will be used. Tk_Uid nameId (in) Description of cursor; see below for possible values. char *source (in) Data for cursor bitmap, in standard bitmap format. char *mask (in) Data for mask bitmap, in standard bitmap format. int width (in) Width of source and mask. | int height (in) Height of source and mask. | int xHot (in) X-location of cursor hot-spot. | int yHot (in) Y-locati... |

getcwd(3c) -- get pathname of current working directory
|
|
getcwd returns a pointer to the current directory pathname. The value of size must be at least one greater than the length of the pathname to be returned. If buf is not NULL, the pathname will be stored in the space pointed to by buf. If buf is a NULL pointer, getcwd will obtain size bytes of space using malloc(3C). In this case, a subsequent call to free should be made using the pointer returned by g... |
|
getdate(3c) -- convert user format date and time
|
|
getdate The getdate function converts a string representation of a date or time into a broken-down time. The external variable or macro getdate_err is used by getdate() to return error values. Templates are used to parse and interpret the input string. The templates are contained in a text file identified by the environment variable DATEMSK. The DATEMSK variable should be se... |

standard/getdcm(3) -- indicates whether depth-cue mode is on or off
|
|
none FUNCTION RETURN VALUE This function can return either of two possible values: FALSE, indicating that the system is not in depth-cue mode. TRUE, indicating that the system is in depth-cue mode. |
|
standard/getdepth(3) -- obsolete routine
|
|
near expects a pointer to the location into which the system should write the distance of the near clipping plane. far expects a pointer to the location into which the system should write the distance of the far clipping plane. |

standard/getdescender(3) -- returns the character characteristics
|
|
none FUNCTION RETURN VALUE The returned value of this function is the length (in pixels) of the longest descender in the current font. |
