DPNS_READLINK(3)					      DPNS Library Functions						  DPNS_READLINK(3)

NAME
dpns_readlink - read value of a symbolic link in the DPNS Name Server SYNOPSIS
#include <sys/types.h> #include "dpns_api.h" int dpns_readlink (const char *path, char *buf, size_t bufsiz) DESCRIPTION
dpns_readlink reads the value of a symbolic link in the DPNS Name Server. path specifies the link name relative to the current DPNS directory or the full DPNS pathname. buf points at a buffer to receive the value. bufsiz gives the buffer size. RETURN VALUE
This routine returns the number of characters put in the buffer if the operation was successful or -1 if the operation failed. In the lat- ter case, serrno is set appropriately. ERRORS
ENOENT The named link does not exist or is a null pathname. EACCES Search permission is denied on a component of the path prefix. EFAULT path or buf is a NULL pointer. ENOTDIR A component of path prefix is not a directory. EINVAL path is not a symbolic link. ENAMETOOLONG The length of path exceeds CA_MAXPATHLEN or the length of a path component exceeds CA_MAXNAMELEN. SENOSHOST Host unknown. SENOSSERV Service unknown. SECOMERR Communication error. ENSNACT Name server is not running or is being shutdown. SEE ALSO

NAME
dpns_chdir - change DPNS current directory used by the name server SYNOPSIS
#include <sys/types.h> #include "dpns_api.h" int dpns_chdir (const char *path) DESCRIPTION
dpns_chdir changes the DPNS current directory used by the name server to expand DPNS pathnames not beginning with /. This current working directory is stored in a thread-safe variable in the client. path specifies the logical pathname relative to the current DPNS directory or the full DPNS pathname. RETURN VALUE
This routine returns 0 if the operation was successful or -1 if the operation failed. In the latter case, serrno is set appropriately. ERRORS
ENOENT The named directory does not exist or is a null pathname. EACCES Search permission is denied on any component of path. EFAULT path is a NULL pointer. ENOTDIR A component of path prefix is not a directory. ENAMETOOLONG The length of path exceeds CA_MAXPATHLEN or the length of a path component exceeds CA_MAXNAMELEN. SENOSHOST Host unknown. SENOSSERV Service unknown. SECOMERR Communication error. ENSNACT Name server is not running or is being shutdown. SEE ALSO
