| <p><a name="index-file-name-errors-913"></a><a name="index-usual-file-name-errors-914"></a> |
| Functions that accept file name arguments usually detect these |
| <code>errno</code> error conditions relating to the file name syntax or |
| trouble finding the named file. These errors are referred to throughout |
| this manual as the <dfn>usual file name errors</dfn>. |
| |
| <dl> |
| <dt><code>EACCES</code><dd>The process does not have search permission for a directory component |
| of the file name. |
| |
| <br><dt><code>ENAMETOOLONG</code><dd>This error is used when either the total length of a file name is |
| greater than <code>PATH_MAX</code>, or when an individual file name component |
| has a length greater than <code>NAME_MAX</code>. See <a href="Limits-for-Files.html#Limits-for-Files">Limits for Files</a>. |
| |
| <p>In the GNU system, there is no imposed limit on overall file name |
| length, but some file systems may place limits on the length of a |
| component. |
| |
| <br><dt><code>ENOENT</code><dd>This error is reported when a file referenced as a directory component |
| in the file name doesn't exist, or when a component is a symbolic link |
| whose target file does not exist. See <a href="Symbolic-Links.html#Symbolic-Links">Symbolic Links</a>. |
| |
| <br><dt><code>ENOTDIR</code><dd>A file that is referenced as a directory component in the file name |
| exists, but it isn't a directory. |
| |
| <br><dt><code>ELOOP</code><dd>Too many symbolic links were resolved while trying to look up the file |
| name. The system has an arbitrary limit on the number of symbolic links |
| that may be resolved in looking up a single file name, as a primitive |
| way to detect loops. See <a href="Symbolic-Links.html#Symbolic-Links">Symbolic Links</a>. |
