NAME

unixerror - handle UNIX run-time error

SYNOPSIS

unixerror()

DESCRIPTION

Unixerror maps the UNIX error number errno (see intro(2)) into the most appropriate BASIC error number as follows:

					UNIX Error				BASIC Error
			1		Not owner		5		Illegal function call
			2		No such file or directory		53		File not found
			5		I/O Error		72		Disk Media Error
			6		No such device or address		71		Disk not Ready
			12		Not enough space		7		Out of memory
			13		Permission denied		5		Illegal function call
			17		File exists		58		File already exists
			21		Is a directory		64		Bad file name
			28		No space left on device		61		Disk full
			30		Read-only file system		70		Disk Write Protect
			33		Math argument		11		Division by zero
			34		Result too large		6		Overflow

All other UNIX errors are mapped into BASIC Error 51: “Internal Error.”

Unixerror then passes the BASIC error number to runerr(err). 

This function is called by many routines in the library when an error is detected by a UNIX system call.
