fopen64_oss(3) Guardian Native C Library Calls Ref
erence Manual
fopen64_guardian() is functionally identical to the fopen64( ) function of the Guardian environ-
ment. It is the same as setting systype guardian at compile time. systype guardian is
the default setting for the C and C++ compilers in the Guardian environment.
To use the fopen64_oss() or fopen64_guardian() functions, specify the _TANDEM_SOURCE
feature test macro.
RETURN VALUES
If the fopen64( ) function succeeds, a pointer to the stream is returned.
If the fopen64( ) function fails, a null pointer is returned, and errno is set to indicate the error.
ERRORS
If any of these conditions occurs, the fopen64( ) function sets errno to the corresponding value.
[EACCES] Search permission is denied on a component of the pathname prefix, or the file
exists and the permissions specified by the mode parameter are denied, or the file
does not exist and write permission is denied for the parent directory of the file to
be created.
[EINTR] The function was interrupted by a signal that was caught.
[EINVAL] The mode parameter is not a valid mode.
[EISDIR] The named file is a directory and mode requires write access.
[EMFILE] The OPEN_MAX file descriptors are currently open in the calling process.
[ENAMETOOLONG]
The length of the path string exceeds PATH_MAX or a pathname component is
longer than NAME_MAX.
[ENFILE] Too many files are currently open in the processor.
[ENOENT] The named file does not exist or the path parameter points to an empty string.
[ENOMEM] Insufficient space to allocate a buffer.
[ENOSPC] The directory or file system that would contain the new file cannot be expanded.
[ENOTDIR] A component of the pathname prefix is not a directory.
[ENOTSUP] The path parameter refers to a file on a logical disk volume administered |
through the Storage Management Foundation (SMF).
[ENXIO] The named file is a character-special or block-special file, and the device associ-
ated with this special file does not exist.
[EOVERFLOW]
The size of the file cannot be represented in an object of type off64_t.
[EROFS] The named file resides on a read-only file system, and mode requires write
access.
[ETXTBSY] The file is being executed, and mode requires write access.
For all other error conditions, errno is set to the appropriate Guardian file-system error number.

Errors and Messages Manual.
