2023-01-15	Remove unnecessary stack allocationsHEAD master	Malfurious	1	-5/+1
	Subtracting esp to allocate space on the stack is only necessary to preserve data that is already lower on the stack. By the time we use either the sockaddr struct or the temporary io buffer, we are finished accessing older stack values, so they can be overwritten. This saves 2 unnecessary instructions from the program. Signed-off-by: Malfurious <m@lfurio.us>
2023-01-14	Write to stdout instead of stdin	Malfurious	1	-2/+3
	The previous version breaks if stdin is directed from a file, such as /dev/null. Signed-off-by: Malfurious <m@lfurio.us>

2023-01-13	Fix error handling for open() call	Malfurious	1	-1/+1
	Zero is a valid return value, so don't jmp to exit if the fd is equal to it. However, we would never expect zero to be returned as stdin is not closed. Signed-off-by: Malfurious <m@lfurio.us>
2023-01-12	Fix bug in exit routine	Malfurious	1	-0/+1
	If an error condition is met during the pipe IO syscalls, eax will be filled with a negative value. We need to then zero the rest of the register before attempting to exit, so we don't continue on to execute garbage. Signed-off-by: Malfurious <m@lfurio.us>
