remove(3) Library Functions Manual remove(3)
NAME
remove - Removes a file
LIBRARY
Standard C Library (libc.so, libc.a)
SYNOPSIS
#include <stdio.h>
int remove( const char *path );
STANDARDS
Interfaces documented on this reference page conform to industry standards as follows:
remove(): POSIX.1, XPG4, XPG4-UNIX
Refer to the standards(5) reference page for more information about industry standards and associated tags.
PARAMETERS
Points to the file to be removed.
DESCRIPTION
The remove() function causes a file named by the pathname pointed to by path to be no longer accessible by that name. A subsequent attempt
to open that file using that name will fail unless it is created anew.
If the path parameter names a directory, remove(path) is equivalent to calling the rmdir() function on that directory. If path does not
name a directory, remove(path) is equivalent to unlink(path).
NOTES
If the file operated upon by the remove() function has multiple hard links, the link count in the file is decremented and only the speci-
fied file name is removed.
RETURN VALUES
Upon successful completion, the remove() function returns 0 (zero). Otherwise, a nonzero value is returned. Refer to the unlink() function
and the rmdir() function for information on return values.
ERRORS
Refer to the unlink() function and the rmdir() function for information on error conditions.
RELATED INFORMATION
Functions: link(2), rename(2), rmdir(2), unlink(2)
