realpath
realpath(3C) Standard C Library Functions realpath(3C)
NAME
realpath - resolve pathname
SYNOPSIS
#include <stdlib.h>
char *realpath(const char *restrict file_name,
char *restrict resolved_name);
DESCRIPTION
The realpath() function derives, from the pathname 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 as a null-terminated string, up to a maximum of {PATH_MAX}
bytes (defined in limits.h(3HEAD)), in the buffer pointed to by resolved_name.
RETURN VALUES
On successful completion, realpath() 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 left in an indeterminate state.
ERRORS
The realpath() function will fail if:
EACCES Read or search permission was denied for a component of file_name.
EINVAL Either the file_name or resolved_name argument is a null pointer.
EIO An error occurred while reading from the file system.
ELOOP Too many symbolic links were encountered in resolving file_name.
ELOOP A loop exists in symbolic links encountered during resolution of the file_name argument.
ENAMETOOLONG The file_name argument is longer than {PATH_MAX} or a pathname component is longer than {NAME_MAX}.
ENOENT A component of file_name does not name an existing file or file_name points to an empty string.
ENOTDIR A component of the path prefix is not a directory.
The realpath() function may fail if:
ENAMETOOLONG Pathname resolution of a symbolic link produced an intermediate result whose length exceeds {PATH_MAX}.
ENOMEM Insufficient storage space is available.
USAGE
The realpath() function operates on null-terminated strings.
Execute permission is required for all the directories in the given and the resolved path.
The realpath() function might fail to return to the current directory if an error occurs.
