realpath
realpath(3) Library Functions Manual realpath(3)
NAME
realpath - Resolves pathname
SYNOPSIS
#include <stdlib.h>
char *realpath(
const char *file_name,
char *resolved_name);
STANDARDS
Interfaces documented on this reference page conform to industry standards as follows:
realpath(): POSIX.1, XPG4-UNIX
Refer to the standards(5) reference page for more information about industry standards and associated tags.
DESCRIPTION
The realpath() function derives, from the file pointed to by file_name, an absolute pathname that names the same file, whose resolution
does not involve ".", "..", or symbolic links. The generated pathname is stored, up to a maximum of PATH_MAX bytes, in the buffer pointed
to by resolved_name.
RETURN VALUES
Upon successful completion, the realpath() function returns a pointer to the resolved name. Otherwise, realpath() returns a null pointer
and sets errno to indicate the error, and the contents of the buffer pointed to by resolved_name are undefined.
ERRORS
If the realpath() function fails, errno may be set to one of the following values: Read or search permission was denied for a component of
file_name. Either the file_name or resolved_name argument is a null pointer. An error occurred while reading from the file system. Too
many symbolic links were encountered in resolving path. The file_name argument is longer than PATH_MAX or a pathname component is longer
than NAME_MAX. A component of file_name does not name an existing file or file_name points to an empty string. Insufficient storage space
available. A component of either path prefix is not a directory.
