int lfc_readlink (const char *path, char *buf, size_t bufsiz)

lfc_readlink reads the value of a symbolic link in the LFC Name Server.

path

specifies the link name relative to the current LFC directory or the full LFC pathname.

buf

points at a buffer to receive the value.

bufsiz

gives the buffer size.

This routine returns the number of characters put in the buffer if the operation was successful or -1 if the operation failed. In the latter case, serrno is set appropriately.

ENOENT

EACCES

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
