i change my c-code
from
to
shouldn't open() be able to override the default permissions already set?
i tried and apparently it does not. is there any reason, besides enforcing security(that the only thing that i could think of)? and is there any way around this? (besides giving the file permissions using the system("chmod "); function?)
What does the system call "dup" do?
What is the difference between dup and dup2

MEGATRON(1) General Commands Manual MEGATRON(1)NAME
megatron, unhex, unbin, unsingle, hqx2bin, single2bin, macbinary - Macintosh file format transformer
SYNOPSIS
megatron [ sourcefile... ]
unbin [ sourcefile... ]
unhex [ sourcefile... ]
unsingle [ sourcefile... ]
hqx2bin [ sourcefile... ]
single2bin [ sourcefile... ]
macbinary [ sourcefile... ]
DESCRIPTION
megatron is used to transform files from BinHex, MacBinary, AppleSingle, or netatalk style AppleDouble formats into MacBinary or netatalk
style AppleDouble formats. The netatalk style AppleDouble format is the file format used by afpd, the netatalk Apple Filing Protocol
(AppleShare) server. BinHex, MacBinary, and AppleSingle are commonly used formats for transferring Macintosh files between machines via
email or file transfer protocols. megatron uses its name to determine what type of tranformation is being asked of it.
If megatron is called as unhex, unbin, or unsingle, it tries to convert file(s) from BinHex, MacBinary, or AppleSingle into AppleDouble
format. BinHex is the format most often used to send Macintosh files by e-mail. Usually these files have an extension of ".hqx". MacBi-
nary is the format most often used by terminal emulators "on the fly" when transferring Macintosh files in binary mode. MacBinary files
often have an extension of ".bin". Some Macintosh LAN-based email packages use uuencoded AppleSingle format to "attach" or "enclose" files
in email. AppleSingle files don't have a standard filename extension.
If megatron is called as hqx2bin, single2bin, or macbinary, it will try to convert the file(s) from BinHex, AppleSingle, or AppleDouble
into MacBinary. This last translation may be useful in moving Macintosh files from your afpd server to some other machine when you can't
copy them from the server using a Macintosh for some reason.
If megatron is called with any other name, it uses the default translation, namely unhex.
If no source file is given, or if sourcefile is `-', and if the conversion is from a BinHex or MacBinary file, megatron will read from
standard input.
The filename used to store any output file is the filename that is encoded in the source file. MacBinary files are created with a ".bin"
extension. In the case of conflicts, the old file is overwritten!
