BASENAME(3) DragonFly Library Functions Manual BASENAME(3)
basename - extract the base portion of a pathname
Standard C Library (libc, -lc)
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.
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
basename(1), dirname(1), dirname(3)
The basename() function conforms to X/Open Portability Guide Issue 4,
Version 2 ("XPG4.2").
The basename() function first appeared in OpenBSD 2.2 and FreeBSD 4.2.
