NAME
dpns_accessr - check existence/accessibility of a file replica
SYNOPSIS
Under Unix: #include <sys/types.h> #include <unistd.h> #include "dpns_api.h" Under Windows/NT: #include <sys/types.h> #define R_OK 4 #define W_OK 2 #define X_OK 1 #define F_OK 0 #include "dpns_api.h" int dpns_accessr (const char *sfn, int amode);
DESCRIPTION
dpns_accessr checks in the name server database the existence or the accessibility of the file replica sfn according to the bit pattern in amode using the real user ID. sfn is either the Site URL or the Physical File Name for the replica. amode the bit pattern is built by an OR of the constants defined in <unistd.h> under Unix or to be explicitly defined under Windows/NT: R_OK test for read permission W_OK test for write permission X_OK test for search/execute permission F_OK test for existence of the file.
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 file does not exist. EACCES Search permission is denied on a component of the parent file prefix, the specified access to the file itself is denied or W_OK is requested but the replica status is not 'P' (cannot modify an existing file). EFAULT sfn is a NULL pointer. EINVAL amode is invalid. ENAMETOOLONG The length of sfn exceeds CA_MAXSFNLEN. SENOSHOST Host unknown. SENOSSERV Service unknown. SECOMERR Communication error. ENSNACT Name server is not running or is being shutdown.
