basename – extract the base portion of a pathname

SYNOPSIS DESCRIPTION IMPLEMENTATION NOTES RETURN VALUES SEE ALSO STANDARDS HISTORY AUTHORS

#include <libgen.h>

char *
basename(char *path);

The basename() function returns the last component from the pathname pointed to by path, deleting any trailing 'amp;/' characters.

This implementation of basename() uses the buffer provided by the caller to store the resulting pathname component. Other vendor implementations may return a pointer to internal storage space instead. The advantage of the former approach is that it ensures thread-safety, while also placing no upper limit on the supported length of the pathname.

If path consists entirely of 'amp;/' characters, a pointer to the string "amp;/" is returned. If path is a null pointer or the empty string, a pointer to the string "amp;." is returned. Otherwise, it returns a pointer to the last component of path.

The basename() function conforms to -xpg4.2.

The basename() function first appeared in OpenBSD 2.2 and FreeBSD 4.2 .

In FreeBSD 12.0, this function was reimplemented to store its result in the provided input buffer. There is no longer any need to use the basename_r() function.
