BASENAME(3) BSD Library Functions Manual BASENAME(3)
basename -- extract the base portion of a pathname
basename(const char *path);
The basename() function returns the last component from the pathname pointed to by path,
deleting any trailing '/' characters. If path consists entirely of '/' characters, a
pointer to the string "/" is returned. If path is a null pointer or the empty string, a
pointer to the string "." is returned.
The basename() function returns a pointer to internal storage space allocated on the first
call that will be overwritten by subsequent calls.
On successful completion, basename() returns a pointer to the last component of path.
If basename() fails, a null pointer is returned and the global variable errno is set to
indicate the error.
The following error codes may be set in errno:
[ENAMETOOLONG] The path component to be returned was larger than MAXPATHLEN.
basename(1), dirname(1), dirname(3)
The basename() function conforms to X/Open Portability Guide Issue 4, Version 2
The basename() function first appeared in OpenBSD 2.2 and FreeBSD 4.2.
