How to check if a file exists in C?
Author
Hello,
In PHP we have the function "file_exists" that returns true in success, e.g.:
And what about C? Which function has a feature like this?
Thanks.
Just try opening it for reading. If it suceeds the file exists.

bool file_exists(const char * filename){ if (FILE * file = fopen(filename, "r")) { fclose(file); return true; } return false;}Alan

FILE *istream;
if ( (istream = fopen ( "file.txt", "r" ) ) == NULL )
{
printf ( "file non-existant!\n" );
}
else
{
printf ( "file exists!\n" );
fclose ( istream );
}
[\code]bool file_exists(const char * filename){ if (FILE * file = fopen(filename, "r")) //I'm sure, you meant for READING =) { fclose(file); return true; } return false;}
For the C++ in you...
std::fstream foo;foo.open("bar");if(foo.is_open() == true) std::cout << "Exist";else std::cout << "Doesn't Exist";

Thanks again for your replies.
And I googled now and found this function:´
#include<sys/stat.h>int file_exists (char * fileName){ struct stat buf; int i = stat ( fileName, &buf ); /* File found */ if ( i == 0 ) { return 1; } return 0; }[google]
Thanks again for your replies.

"open" and "stat" are a bit of an overkill.
"access" is a much lighter function..
Add one more vote on 'access'.
