remove is a function in C programming language that removes a certain file. It is included in the C standard library header file stdio.h.

The prototype of the function is as follows:

int remove ( const char * filename );

If successful, the function returns zero. Nonzero value is returned on failure and errno variable is set to corresponding error code.

Sample usage

The following program demonstrates common usage of remove:

#include <stdio.h>
int main() {
    const char *filename = "a.txt";
    remove (filename);
    return 0;
    }

remove can be used to remove the C executable after it has finished running where int argc, *char argv refer to the number and value of the command-line arguments where argv is the first argument, i.e. the name of the executable:

#include <stdio.h>
int main(int argc, *char argv)
{
    printf("Now removing the file %s.\n", argv);
    remove(argv);
    return 0;
}
