lfc_readlink - read value of a symbolic link in the LFC Name Server
#include <sys/types.h> #include "lfc_api.h" 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 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.
