To erase a file, you use the library function remove(). Syntax Its prototype is in STDIO.H, as follows: int remove(const char *filename); Argument The variable *filename is a pointer to the name of the file to be erased. (See the section on filenames earlier in this unit.) The specified file must not be open. If the file exists, it is erased (just as if you used the DEL command from the DOS prompt) and remove() returns 0. Return Value If the file does not exist, is write-only, or some other error occurs, remove() returns -1. |
