Prototype

int remove(const char *filename);

int _wremove(const wchar_t *filename);

Description

Removes a file.

remove deletes the file specified by filename. It is a macro that simply translates its call to a call to unlink. If your file is open, be sure to close it before removing it.

The filename string can include a full path.

Return Value

On successful completion, remove returns 0. On error, it returns -1, and the global variable errno is set to one of the following values:

EACCES	Permission denied
ENOENT	No such file or directory

Example

 #include <stdio.h>
 int main(void)
 {
     char file[80];
     /* prompt for file name to delete */
     printf("File to delete: ");
     gets(file);
     /* delete the file */
     if (remove(file) == 0)
        printf("Removed %s.\n",file);
     else
        perror("remove");
     return 0;
 }
