Given a file path, we have to check whether a specified file exist or not using the access() function.
Program:
The source code to check a specified file exists or not using the access() function is given below. The given program is compiled and executed using GCC compile on UBUNTU 18.04 OS successfully.
// C program to check whether a specified file exist
// or not using access() function
#include <stdio.h>
#include <unistd.h>
int main(void)
{
int isFileExist = 0;
isFileExist = access("includehelp.txt", F_OK);
if (isFileExist != -1) {
printf("file exists.\n");
return 1;
}
printf("file does not exists.\n");
return 0;
}
Output:
file exists.
Explanation:
Here, we checked file "includehelp.txt" exists in the current directory or not using the access() function. Then printed the appropriate message on the console screen.
