realpath(3) |
 |
realpath − returns the canonicalized absolute pathname.
#include
<sys/param.h>
#include <unistd.h>
char *realpath(char *path, char resolved_path[]);
realpath expands all symbolic links and resolves references to ’/./’, ’/../’ and extra ’/’ characters in the null terminated string named by path and stores the canonicalized absolute pathname in the buffer of size MAXPATHLEN named by resolved_path. The resulting path will have no symbolic link, ’/./’ or ’/../’ components.
If there is no error, it returns a pointer to the resolved_path.
Otherwise it returns a NULL pointer and places in resolved_path the absolute pathname of the path component which could not be resolved. The global variable errno is set to indicate the error.
