The directory file descriptor should not be used or closed following a successful function call, as this might cause undefined results from future operations on the directory stream obtained from the call. Use \fBclosedir\fR(3C) to close a directory stream. .sp .LP The directory stream is positioned at the first entry. If the type \fBDIR\fR is implemented using a file descriptor, applications will only be able to open up to a total of {\fBOPEN_MAX\fR} files and directories. A successful call to any of the \fBexec\fR functions will close any directory streams that are open in the calling process. See \fBexec\fR(2). .SH RETURN VALUES .sp .LP Upon successful completion, \fBopendir()\fR and \fBfdopendir()\fR return a pointer to an object of type \fBDIR\fR. Otherwise, a null pointer is returned and \fBerrno\fR is set to indicate the error. .SH ERRORS .sp .LP The \fBopendir()\fR function will fail if: .sp .ne 2 .mk .na \fB\fBEACCES\fR\fR .ad .RS 16n .rt Search permission is denied for the component of the path prefix of \fIdirname\fR or read permission is denied for \fIdirname\fR. .RE .sp .ne 2 .mk .na \fB\fBELOOP\fR\fR .ad .RS 16n .rt Too many symbolic links were encountered in resolving \fIdirname\fR. .RE .sp .ne 2 .mk .na \fB\fBENAMETOOLONG\fR\fR .ad .RS 16n .rt The length of the \fIdirname\fR argument exceeds {\fBPATH_MAX\fR}, or a path name component is longer than {\fBNAME_MAX\fR} while {\fB_POSIX_NO_TRUNC\fR} is in effect. .RE .sp .ne 2 .mk .na \fB\fBENOENT\fR\fR .ad .RS 16n .rt A component of \fIdirname\fR does not name an existing directory or \fIdirname\fR is an empty string. .RE .sp .ne 2 .mk .na \fB\fBENOTDIR\fR\fR .ad .RS 16n .rt A component of \fIdirname\fR is not a directory. .RE .sp .LP The \fBfdopendir()\fR function will fail if: .sp .ne 2 .mk .na \fB\fBENOTDIR\fR\fR .ad .RS 11n .rt The file descriptor \fIfildes\fR does not reference a directory. .RE .sp .LP The \fBopendir()\fR function may fail if: .sp .ne 2 .mk .na \fB\fBEMFILE\fR\fR .ad .RS 16n .rt There are {\fBOPEN_MAX\fR} file descriptors currently open in the calling process. .RE .sp .ne 2 .mk .na \fB\fBENAMETOOLONG\fR\fR .ad .RS 16n .rt Pathname resolution of a symbolic link produced an intermediate result whose length exceeds \fBPATH_MAX\fR. .RE .sp .ne 2 .mk .na \fB\fBENFILE\fR\fR .ad .RS 16n .rt Too many files are currently open on the system. .RE .SH USAGE .sp .LP The \fBopendir()\fR and \fBfdopendir()\fR functions should be used in conjunction with \fBreaddir\fR(3C), \fBclosedir\fR(3C) and \fBrewinddir\fR(3C) to examine the contents of the directory (see the \fBEXAMPLES\fR section in \fBreaddir\fR(3C)). This method is recommended for portability. .SH ATTRIBUTES .sp .LP See \fBattributes\fR(7) for descriptions of the following attributes: .sp .TS tab( ) box; cw(2.75i) |cw(2.75i) lw(2.75i) |lw(2.75i) .
