BASENAME(3) Library Functions Manual BASENAME(3) NAME basename -- return the last component of a pathname LIBRARY Standard C Library (libc, -lc) SYNOPSIS #include <libgen.h> char * basename(char *path); DESCRIPTION The basename() function takes the pathname pointed to by path and returns a pointer to the final component of the pathname, deleting any trailing `/' characters. If path consists entirely of `/' characters, basename() returns a pointer to the string ``/''. If path is a null pointer or points to an empty string, basename() returns a pointer to the string ``.''. RETURN VALUES The basename() function returns a pointer to the final component of path. SEE ALSO basename(1), dirname(3) STANDARDS o X/Open Portability Guide Issue 4, Version 2 (``XPG4.2'') o IEEE Std 1003.1-2001 (``POSIX.1'') BUGS If the length of the result is longer than PATH_MAX bytes (including the terminating nul), the result will be truncated. The basename() function returns a pointer to static storage that may be overwritten by subsequent calls to basename(). This is not strictly a bug; it is explicitly allowed by IEEE Std 1003.1-2001 (``POSIX.1''). NetBSD 7.1.2 May 10, 2008 NetBSD 7.1.2
