extract the base portion of a
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.
On successful completion,
returns a pointer to the last component of path.
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:
- The path component to be returned was larger than
basename(1), dirname(1), dirname(3)
basename() function conforms to
X/Open Portability Guide Issue 4, Version 2
basename() function first appeared in
Todd C. Miller
basename() returns a pointer to internal
static storage space that will be overwritten by subsequent calls.
Other vendor implementations of
may modify the contents of the string passed to
basename(); this should be taken into account when
writing code which calls this function if portability is desired.
