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 and 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;
}
