Is using fseek to backtrack character fscanf operations reliable? Like for example if I have just fscanf-ed 10 characters but I would like to backtrack the 10 chars can I just fseek(infile, -10, SEEK_CUR) ? For most situations it works but I seem to have problems with the character ^M. Apparently fseek registers it as a char but fscan...
I am using CreateProcess to create a cmd.exe process that is passed a parameter that it executes and quits, this makes command prompt flash up on the screen.

I want to create a read-eval-print loop using flex/bison parser. Trouble is, the flex generated lexer wants input of type FILE* and i would like it to be char*. Is there anyway to do this?

I have client/server program in C, through which I am transferring files to the client from server. But the client is waiting for recv even after receiving the last byte of the file.

If I want to convert a single numeric char to it's numeric value, for example, if: char c = '5'; and I want c to hold 5 instead of '5', is it 100% portable doing it like this? c = c - '0'; I heard that all character sets store the numbers in consecutive order so I assume so, but I'd like to know if there is an organized library fun...

Using Visual Studio 9 on Windows 64 with Intel Fortran 10.1 I have a C function calling Fortran, passing a literal string "xxxxxx" (not null terminated) and the hidden passed length arg 6. Fortran gets it right since the debugger recognizes it's a character(6) var and has the correct string, but when I try to assign another Fortran cha...
Greetings, I am trying to learn pointers in C, I simply want my "addtwo" function to add 2 to every element of the input integer array, yet I get odd compilation errors, here is the non-pointer version which indeed won't properly compile. addtwo(int *arr[]) { int i=0; for(;i< sizeof(arr)/sizeof(int);i++) { arr[i] = arr[i...
