Open File with Fopen, Given Absolute Path on Windows

Open file with fopen, given absolute path on Windows

Use double slashes:

"C:\\Documents and Settings\\juegos psps.txt"

An absolute path in fopen()

fopen() can take absolute paths as arguments. Are you working on a unix/linux based OS or on windows? Likely what is happening is you've got the path wrong. If you're on a mac, which it looks like you are, the correct path might be

~/Documents/projects/cs50_radio/broadcast/source/deadinside.mp3

But you can verify by cd'ing into the directory and typing pwd

If you're on windows, your path is definitely wrong, as windows would look more like this:

C:\Documents\projects\cs50_radio\broadcast\source\deadinside.mp3

C fopen() - Possible issue with absolute path

You're returning the address of a local variable in getFileName, which results in undefined behavior.
This is a common pitfall in C.

You need to either:
A) Allocate the string on the heap (using e.g. malloc) and return it.
B) Have getFileName take a pointer to a caller-allocated buffer which it then populates.

Also, when debugging problems like this, don't just assume everything is working. Use printf to see what the value of filename is before you try to fopen it.

C++ fopen relative Path

Relative paths are relative to the current working directory, not the path of the executable. The current working directory is the directory from which you started the program.

To treat a path as relative to the position of the executable, the simplest portable option is to access the executable as argv[0], extract the directory, and chdir() into it. Note that this will work only as long as the program was itself started with the full path name.

C fopen can't open absolute path OS X

file://localhost/Users/macuser/test.txt is a URI, not a file path. Process the string to strip out everything up to and including /localhost and it should be fine.

Note that this sort of solution will only work if there are no escape sequences in the URI. As noted below, it may be simpler to send the path from the Objective C side.

Unable to access file from share drive using fopen in C (windows)

You need to escape the backslash in filepath during compile time.. i.e.
"\xyz\abc.txt" but runtime has only one slash.

Piece of code to read input from user:

char filename[50];
FILE *fp;

printf("Enter the filename \n");
gets(filename);

fp = fopen(filename, "r");
