| .SH "NAME" | ||
| uri_absolute \- determine whether the path in a URI is relative or absolute | ||
| .SH "LIBRARY" | ||
| .PP | ||
| URI parsing library (liburi, \-luri) | ||

| .SH "DESCRIPTION" | ||
| .PP | ||
| The | ||
| \fBuri_absolute_path\fR | ||
| function determines whether the path in a parsed URI is absolute or relative\&. An absolute path is one begins with a "/" character\&. | ||
| .PP | ||
| URIs which do not include a path at all are not considered to be absolute by this function\&. Any URI which does include a path and for which | ||
| \fBuri_absolute\fR(3) | ||
| returns | ||
| 1 | ||
| will be determined to have an absolute path\&. More specifically, any URI which includes either a scheme or a hostname as well as a path are always considered to have an absolute path (that is, | ||
| file:foo | ||
| and | ||
| file:/foo | ||
| will give the same results after parsing)\&. | ||
| .SH "PARAMETERS" | ||
| .PP | ||
| \fIuri\fR | ||
| .RS 4 | ||
| The URI to evaluate\&. | ||
| .RE | ||
| .SH "RETURN VALUE" | ||
| .PP | ||
| If successful, | ||
| \fBuri_absolute_path\fR | ||
| returns | ||
| 1 | ||
| if | ||
| \fIuri\fR | ||
| contains a URI with an absolute path, and | ||
| 0 | ||
| otherwise\&. | ||
| .PP | ||
| If an error occurs, | ||
| \fBuri_absolute\fR | ||
| returns | ||
| \-1, and sets | ||
| \fIerrno\fR | ||
| accordingly\&. | ||
