#include <sys/types.h> #include "dpns_api.h" int dpns_symlink (const char *target, const char *linkname)
dpns_symlink makes a symbolic link to a file or a directory in the DPNS Name Server. linkname specifies the link name relative to the current DPNS directory or the full DPNS pathname.
This routine returns 0 if the operation was successful or -1 if the operation failed. In the latter case, serrno is set appropriately.

EFAULT target or linkname is a NULL pointer. EEXIST linkname exists already. ENOTDIR A component of linkname prefix is not a directory. ENOSPC The name server database is full. ENAMETOOLONG The length of target or linkname exceeds CA_MAXPATHLEN or the length of a linkname component exceeds CA_MAXNAMELEN. SENOSHOST Host unknown. SENOSSERV Service unknown. SECOMERR Communication error. SELOOP Too many symbolic links encountered when parsing linkname. ENSNACT Name server is not running or is being shutdown.
