I have been told by a professor that you can get a file's last modification time by using utime.h. However, the man page seem to cite that utime() only sets this value. How can I look up the last time a file was changed in C on a UNIX system? ...
Hi, Is there any Microsoft API for parallel programing in C language ? thanks for any answers, bye ...
I am trying to read the .wav file and give the raw data as input to the FFT algorithm.I have used the following code to read the .wav file. char ChunkID[4], Format[4], Subchunk1ID[4],Subchunk2ID[4]; int ChunkSize,Subchunk1Size, SampleRate, ByteRate,Subchunk2Size; short AudioFormat, NumChannels, BlockAlign, BitsPerSample; short *Data; /...
I unfortunately have several macros left over from the original version of my library that employed some pretty crazy C. In particular, I have a series of macros that expect certain types to be passed to them. Is it possible to do something along the lines of: static_assert(decltype(retval) == bool); And how? Are there any clever alte...

HI, I am using loadImage to load an 24bit bmp file and then try to get the bmp info hBitmap = (HBITMAP)LoadImage(NULL, "logo.bmp", IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE | LR_DEFAULTSIZE) GetObject( hBitmap, sizeof(BITMAP), &bm ); When I do the same operation with windows color display setting 32 hi color than i got ...
There are many good packages for calculating the intersection of polygons. I have found the GPC library useful. I would like to compute intersections of polyhedra (piecewise linear boundaries) in 3D. Are there any good libraries in C/C++ for this? ...
I have a struct which is a node, and another which is a list of these nodes. In the list struct, its an array of nodes, but instead of an array, it's a pointer to pointer with a size integer: typedef struct node { struct node *next; MyDef *entry; } Node; typedef struct list { Node **table; int size; } List; List *init...
I know that there is a long debate regarding this matter. I also understand that this is strictly not a programming question. But I am asking here as this platform contains wide range of experts from different realms. When we got admitted in a Computer Science and Engineering(CSE) course in university, we were first taught C. The cours...
Just trying to make a kind of hash table with each node being a linked list. Having trouble just initializing the space, what am I doing wrong? #include <stdlib.h> typedef struct entry { struct entry *next; void *theData; } Entry; typedef struct HashTable { Entry **table; int size; } HashTable; int main(){ HashTable *ml; ml =...
I am coming across situations such as this: if(x == NULL) { printf(" The value of X is Null, exiting.."); return -1; } and this "situation" gets repeated many , many times..... laziness aside is there a better way to write this ? Cheers! ...
I created a structure to represent a fixed-point positive number. I want the numbers in both sides of the decimal point to consist 2 bytes. typedef struct Fixed_t { unsigned short floor; //left side of the decimal point unsigned short fraction; //right side of the decimal point } Fixed; Now I want to add two fixed point number...
If I have a structure such as typedef struct _people { char *name; bool *exists; struct _people **citizens; } PEOPLE; How do I go about allocating memory so that people->citizens[0]->name is accessible? I've tried info->citizens = malloc(sizeof(PEOPLE *)*numbPeople); However when I try to access info->citizens->name I get th...
From the man page on my system: void *memmove(void *dst, const void *src, size_t len); DESCRIPTION The memmove() function copies len bytes from string src to string dst. The two strings may overlap; the copy is always done in a non-destructive manner. From the C99 standard: 6.5.8.5 When tw...
Hi I have this code int x,y,m; for(;;){ m=scanf("%d %d",&x,&y); if (m!=2 || m==EOF){ break; } else{ printf("/%d/%d/\n",x,y); } } if (feof ( stdin )){ printf("End of input\n"); }else if(m!=2){ printf("There was an error\n"); } Under linux ctrl+D indicates end of input , and for windows ctr...
hello i am having a trouble in taking input for the character type in c.the behavior of my source code is unusual. my code is: int n,i; char *ps; printf("Total no:"); scanf("%d",&n); ps=(char *)calloc(n,sizeof(char)); for(i=0;i<n;i++) { printf("Enter character %d:",i+1); scanf("%c",ps+i); } then as per my requirement it...

Hi All. What is the correct way to find out if a process is running as the SYSTEM user. I'm looking for a win32 C API to check for the system user. We used to check if the username was "SYSTEM", but since Windows Server 2008 R2 the SYSTEM user appears to be localised. I.e SYSTEEM on a Dutch system. I cant find much information about...
hello i am having trouble with this c language code: char st[2]; printf("enter first value:"); scanf("%c", &st[0]); printf("enter second value:"); scanf("%c", &st[1]); So my computer didn't ask me to enter the second value, I mean to say that it only print the first printf statement then I enter a character and then it only pr...
