在下文中一共展示了L_WARNING函数的20个代码示例,这些例子默认根据受欢迎程度排序。您可以为喜欢或者感觉有用的代码点赞,您的评价将有助于我们的系统推荐出更棒的C++代码示例。

示例1: lqueueDestroy

/*!
 *  lqueueDestroy()
 *
 *      Input:  &lqueue  (<to be nulled>)
 *              freeflag (TRUE to free each remaining struct in the array)
 *      Return: void
 *
 *  Notes:
 *      (1) If freeflag is TRUE, frees each struct in the array.
 *      (2) If freeflag is FALSE but there are elements on the array,
 *          gives a warning and destroys the array.  This will
 *          cause a memory leak of all the items that were on the queue.
 *          So if the items require their own destroy function, they
 *          must be destroyed before the queue.  The same applies to the
 *          auxiliary stack, if it is used.
 *      (3) To destroy the L_Queue, we destroy the ptr array, then
 *          the lqueue, and then null the contents of the input ptr.

示例18: convertFilesToPS

/*
 *  convertFilesToPS()
 *
 *      Input:  dirin (input directory)
 *              substr (<optional> substring filter on filenames; can be NULL)
 *              res (typ. 300 or 600 ppi)
 *              fileout (output ps file)
 *      Return: 0 if OK, 1 on error
 *
 *  Notes:
 *      (1) This generates a PS file for all image files in a specified
 *          directory that contain the substr pattern to be matched.
 *      (2) Each image is written to a separate page in the output PS file.
 *      (3) All images are written compressed:
 *              * if tiffg4  -->  use ccittg4
 *              * if jpeg    -->  use dct
 *              * all others -->  use flate
 *          If the image is jpeg or tiffg4, we use the existing compressed
 *          strings for the encoding; otherwise, we read the image into
 *          a pix and flate-encode the pieces.
 *      (4) The resolution is often confusing.  It is interpreted
 *          as the resolution of the output display device:  "If the
 *          input image were digitized at 300 ppi, what would it
 *          look like when displayed at res ppi."  So, for example,
 *          if res = 100 ppi, then the display pixels are 3x larger
 *          than the 300 ppi pixels, and the image will be rendered
 *          3x larger.
 *      (5) The size of the PostScript file is independent of the resolution,
 *          because the entire file is encoded.  The res parameter just
 *          tells the PS decomposer how to render the page.  Therefore,
 *          for minimum file size without loss of visual information,
 *          if the output res is less than 300, you should downscale
 *          the image to the output resolution before wrapping in PS.
 *      (6) The "canvas" on which the image is rendered, at the given
 *          output resolution, is a standard page size (8.5 x 11 in).
