sqrtl(), etc. for Cygwin 29 30 (11/7/2012 6:40:56 PM) comp.lang.c I've been using Cygwin lately, and am largely satisfied. It has gcc, but lacks sqrtl(), atan2l(), etc. What's the recommended remedy? I Googled "source sqrtl" and got to codeforge.com but only AFTER passi... James

Programming challenge: Combination encoding 9 25 (10/23/2010 7:11:26 AM) comp.programming In comp.compression, in a thread titled "Encode combination efficiently", I pose a programming challenge. Refer to that thread for details, but briefly: Let A and B be large integers (you may assume they're ... James

Reusable source code 74 304 (9/6/2010 5:48:24 PM) comp.lang.c Jacob's mention of his library reminds me of my own suggestion to help with software reusability. Much software has the form High Level -- application-specific code Mid Level -- application-specific... James

Questions about random compression 7 29 (6/16/2010 7:07:54 PM) comp.compression This post may say nothing that's not been said in this ng before, but we do have some newcomers who are asking for enlightenment and respect. I will pose five questions. Working on the answers to these five qu... James

Optimization idea: put (y&1) in [] instead of if() 14 33 (11/4/2009 9:40:45 AM) comp.lang.c Is it OK to discuss C programming in this ng? :-) :-) I just stumbled on an optimization which surprised me, though I'm sure it's "old hat" to many of you. An interest in random-number generation was kind... James

When shorts are longer than longs ! 185 24 (5/12/2009 9:27:02 AM) comp.lang.c I've hardly ever used bitfields, but now have an application where a union of different bitfielded structures seems like the proper solution. For example, union { struct { unsigned long f... James

First Inventor of Programming Method 4 29 (9/16/2008 6:33:51 AM) comp.programming Ever wonder who the very first inventor of some programming method was? John von Neumann is credited with PRNG's and merge-sort among other techniques. Correct? Who invented hash tables? Some inventions ar... James

What does this code do? #2 20 31 (2/6/2008 4:58:24 AM) comp.lang.c How about this idea? Post fragments of C code which seem fun, interesting or instructive. Puzzles can be posed in various ways. (What does this do? Can you see the bug? How to code this for better efficie... James

Compression identical to its inverse? 13 69 (11/26/2007 7:58:30 AM) comp.compression (This is not a practical comment or question, but just a puzzle that might intrigue. I'd post it to rec.puzzles instead, but readers of this group are more likely to have the requisite background.) Show a com... James

Space-efficient Hash Tables 2 26 (8/20/2007 6:03:51 AM) comp.programming Several recent posts dealt with Hash Tables, but one of the most interesting topics has been ignored: Space efficency. (I realize this topic is irrelevant in many applications, either because the table is smal... James

inline functions #4 57 36 (11/24/2012 12:20:34 PM) comp.lang.c Is there a way of controlling which functions are inlined, or likely to be inlined, and which ones you never want inlined? Especially with gcc... (I have a file with over 300 functions, each of which is ca... bc (2211)

Macros #8 29 37 (12/2/2012 5:53:27 PM) comp.lang.c I'm trying out these macros to save on typing and errors** : #define else } el##se { That seems to work: 'else' is converted to '} else {'. Somehow the ## stops the new 'else' from being recursively proc... bc (2211)

Command line arguments 136 31 (1/10/2013 8:58:16 PM) comp.lang.c I've just discovered that a single command line argument containing wildcards, such as *.c, is expanded to a full list of matching files before it gets to main(). That isn't really what I want (and there c... bc (2211)

Assigning an array to another array using C's assignment operator 13 15 (1/31/2013 10:49:45 PM) comp.lang.c Hi, Here is one technique I have thought of to allow the assignment of one array to another in an indirect manner as it's not allowed directly in C. Before all, I would like to clarify that it's not someth... raghavanil4m (37)

Reverse of gmtime? 33 21 (2/5/2013 11:02:16 AM) comp.lang.c The gmtime function in header converts the calendar time pointed to by some pointer to time_t into a broken-down time, expressed as UTC. Is there a canonical way to do the reverse? Francois Grieu... fgrieu (251)
