REALPATH Section: Linux Programmer's Manual (3) Updated: July 29th 1994 Index   NAME realpath - returns the canonicalized absolute pathname.   SYNOPSIS #include <sys/param.h> #include <unistd.h> char *realpath(char *path, char resolved_path[]);   DESCRIPTION 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.   RETURN VALUE 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.   ERRORS ENOTDIR A component of the path prefix is not a directory. EINVAL The pathname contains a character with the high-order bit set. ENAMETOOLONG A component of a pathname exceeded MAXNAMLEN characters, or an entire path name exceeded MAXPATHLEN characters. ENOENT The named file does not exist. EACCES Search permission is denied for a component of the path prefix. ELOOP Too many symbolic links were encountered in translating the pathname. EIO An I/O error occurred while reading from the file system.   SEE ALSO   Index NAME SYNOPSIS DESCRIPTION RETURN VALUE ERRORS SEE ALSO This document was created by using the manual pages.
