NAMErfio_chmod, rfio_fchmod - change access mode of a directory/file
SYNOPSIS#include <sys/types.h> #include "rfio_api.h" int rfio_chmod (const char *path, mode_t mode); int rfio_fchmod (int s, mode_t mode);
DESCRIPTIONrfio_chmod sets the access permission portion of the mode of a directory/file to the bit pattern in mode. rfio_fchmod is identical to rfio_chmod but works on the file descriptor s returned by rfio_open. path specifies the logical pathname relative to the current directory or the full path‐ name. mode is constructed by OR'ing the bits defined in <sys/stat.h> under Unix or "stat‐ bits.h" under Windows/NT: S_IRUSR 0000400 read by owner S_IWUSR 0000200 write by owner S_IXUSR 0000100 execute/search by owner S_IRGRP 0000040 read by group S_IWGRP 0000020 write by group S_IXGRP 0000010 execute/search by group S_IROTH 0000004 read by others S_IWOTH 0000002 write by others S_IXOTH 0000001 execute/search by others The effective user ID of the process must match the owner of the file or be super-user. If a directory is writable and has the sticky bit set, files/directories within that directory can be removed or renamed only if: the effective user ID of the requestor matches the owner ID of the file or the effective user ID of the requestor matches the owner ID of the directory or the file is writable by the requestor or the requestor is super-user.
RETURN VALUEThis routine returns 0 if the operation was successful or -1 if the operation failed. In the latter case, serrno is set appropriately.
ERRORSEPERM The effective user ID does not match the owner of the file and is not super- user. ENOENT The named file/directory does not exist or is a null pathname. EBADF s is not a valid file descriptor. EACCES Search permission is denied on a component of the path prefix or write per‐ mission on the file itself is denied. EFAULT path is a NULL pointer. ENOTDIR A component of path prefix is not a directory. 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.
