Hi everyone, I have a simple design(?) question. I'm writing a simple program, that has a couple of functions that look like these. float foo (float* m,size_t n){ float result; //do some calculations, for example a sum return result / n; } I have a couple of questions on this, with no intention of re opening some holy ...
I have an int pointer (int *count) if i want to increment the integer being pointed at using ++ I thought I would call *count++; However, I am getting a build warning "expression result unused". I can call *count += 1; But, I would like to know how to use the ++. Any ideas? ...
I have never been good at playing with pointers in C. But this time I would like to ask for your help to resolve my problems with pointers. I have a function here to push a value into a stack. void StackPush(stackT *stackPtr, stackElementT element){ stackNodeT* node = (stackNodeT *) malloc(sizeof(stackNodeT)); if (node == NULL){ ...
I have a server thats sending out data records as strings of varying length(for eg, 79,80,81,82) I want to be able to receive exactly one record at a time.I've delimited records with a (r) but because I dont know howmany bytes I have to receive, It sometimes merges records and makes it difficult for me to process. ...
Hi experts~ I heard a lot that data should be properly aligned in memory for better access efficiency. CPU access memory on a word boundary. So in the following scenario, the CPU has to make 2 memory accesses to get a single word. Supposing: 1 word = 4 bytes ("|" stands for word boundary. "o" stands for byte boundary) |----o----o...

I am trying to find out filetypes using c code, here is the code char *get_file_type(char *path, char *filename) { FILE *fp; char command[100]; char file_details[100]; char *filetype; sprintf(command, "file -i %s%s", path, filename); fp = popen(command, "r"); if (fp == NULL) { printf("Failed to run c...
When executing a bash script located on my FUSE filesystem, an open() call is made with these flags: debug,cpfsfuse.c(62),cpfs_fuse_open: path "/make.sh", flags 0100040 The flags (0100040) should correspond to those passed in parameter 2 of open(). The unknown flag originates from an execve() call: matt@stanley:~/cpfs/dir$ strace -f ....

Hi, I have to start off by saying I have very little idea on this topic so humor me if i seem ignorant. Due to the problem of having to use a vc++ library in a g++ compiled program, I built a local server-client system where the server is compiled in vc++ and the client in g++ and they interact through sockets. A lot of data transfer o...
