FUNCTIONS ^

lex_error

Emit an error message.

dupstr

The C89 standard does not define a dupstr() in the C library, so define our own dupstr. Function names beginning with "str" are reserved (I think), so make it dupstr, as that is what it does: duplicate a string.

init_global_state

create and initialize a global_state structure, containing all 'global' variables that are needed during the scanning.

destroy_global_state

free all memory of the global state structure.

main

Entry point of the heredoc pre-processor.
