Function Documentation

asm_lex_token* asm_lex_input_file	(	FILE *	input,
		int *	errors
	)

Parses an entire input file into a single lexical token stream.

Parameters

input	- The input file with the seeker at the beginning of the file.
errors	- pointer to an error counter.

Returns

The head of a linked list of lexer tokens representing the parsed file.
