lfc_readdir - read LFC directory opened by [1mlfc_opendir [22min the name
[1mstruct dirent *lfc_readdir (lfc_DIR *[4m[22mdirp[24m[1m)[0m
[1mlfc_readdir [22mreads the LFC directory opened by [1mlfc_opendir [22min the name
server. This routine returns a pointer to a structure containing the
current directory entry. [1mlfc_readdir [22mcaches a variable number of such
entries, depending on the filename size, to minimize the number of
requests to the name server.
[4mdirp[24m specifies the pointer value returned by [1mlfc_opendir[22m.
Only the fields d_name, d_reclen and on some platforms d_namlen are
This routine returns a pointer to a structure containing the current
directory entry if the operation was successful or NULL if the end of
the directory was reached or if the operation failed. When the end of
the directory is encountered, serrno is not changed. If the operation
failed, [1mserrno [22mis set appropriately.
As lfc_readdir returns a null pointer both at the end of the directory
and on error, an application wishing to check for error situations
should set [1mserrno [22mto 0, then call lfc_readdir, then check [1mserrno [22mand if
it is non-zero, assume an error has occurred.
[1mEBADF [22mFile descriptor in DIR structure is invalid.
[1mEFAULT [4m[22mdirp[24m is a NULL pointer.
[1mSECOMERR [22mCommunication error.
[1mENSNACT [22mName server is not running or is being shutdown.
