File and Path Function

int open64(const char *filename, int flags[, mode_t mode]);

Internationalization (I18n) Function Overview

This function is similar to open. It returns a file descriptor which can be used to access the file named by filename. The only difference is that on 32 bit systems the file is opened in the large file mode. I.e., file length and file offsets can exceed 31 bits.

I18n Issues

On ANSI UTF-16 platforms, use a conversion function to convert the wide-character string to a multibyte-character string and then call open64.

See Pathnames for a discussion of path and filename considerations in an internationalized application, and File I/O, which addresses reading and writing non-ASCII text data files.

Recommended Replacements*

ANSI UTF-8	open64
ANSI UTF-16	convert and call open64
