lfc_setfsize - set filesize for a regular file; set also last modification time to the current time
#include <sys/types.h> #include "lfc_api.h" int lfc_setfsize (const char *path, struct lfc_fileid *file_uniqueid, u_signed64 filesize) int lfc_setfsizec (const char *path, struct lfc_fileid *file_uniqueid, u_signed64 filesize, const char *csumtype, char *csumvalue)
lfc_setfsize sets the filesize for a regular file; set also the last modification time to the current time. This function should only be called by the stager after the last write operation has been performed on the file. The file can be identified by path name or by file_uniqueid. If both are specified, file_uniqueid is used. path specifies the logical pathname relative to the current LFC directory or the full LFC pathname. csumtype specifies the type of checksum. Valid types are: CS standard 32 bits checksum AD Adler 32 bits checksum MD MD5 128 bits checksum
This routine returns 0 if the operation was successful or -1 if the operation failed. In the latter case, serrno is set appropriately.
ENOENT A component of path prefix does not exist or path is a null pathname. EACCES Search permission is denied on a component of the path prefix or the caller effective user ID does not match the owner ID of the file or write permission on the file itself is denied. EFAULT path and file_uniqueid are NULL pointers. ENOTDIR A component of path prefix is not a directory. EISDIR The file is not a regular file. EINVAL The length of the csumtype exceeds 2 or csumtype is an unknown type or the length of the csumvalue exceeds 32. 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.
