You have four lex-generated files - go intothose files and mark all of the functions in them static - this makes their scope local to the C file they live in. Next create a wrapper function that is NOT static.
in file1.c create scanner1() which calls the yylex function or whatever entrypoint you have defined. Create scanner2(), scanner3() and scanner4() in each of ther other files. In the main block, have for extern declarations for scanner1() scanner2() etc.
ld will hide the fact that each of those four modules has functions all named the same:

Hi there,
I am trying to figure out a way to combine multiple sources with different data on a single file, and I am trying to find the best way to do it.
I have multiple files, let's say A, B, C and D. A has a field in common with B, B has a field in common with C, and C has a field in... (2 Replies)

Once a time, I did see a way to multiply a file input in bash, but have forgotten how it was done.
Eks.
awk 'FNR==NR {a++;next} ($2 in a) {print $2}' file file
Here you need file two times.
I seen it some like this
awk 'FNR==NR {a++;next} ($2 in a) {print $2}' 2&file (16 Replies)

GM,
I have an issue at work, which requires a simple solution. But, after multiple attempts, I have not been able to hit on the code needed.

megaco_flex_scanner(3erl) Erlang Module Definition megaco_flex_scanner(3erl)NAME
megaco_flex_scanner - Interface module to the flex scanner linked in driver.
DESCRIPTION
This module contains the public interface to the flex scanner linked in driver. The flex scanner performs the scanning phase of text mes-
sage decoding.
The flex scanner is written using a tool called flex . In order to be able to compile the flex scanner driver, this tool has to be avail-
able.
By default the flex scanner reports line-number of an error. But it can be built without line-number reporting. Instead token number is
used. This will speed up the scanning some 5-10%. Use --disable-megaco-flex-scanner-lineno when configuring the application.
The scanner will, by default, be built as a reentrant scanner if the flex utility supports this (it depends on the version of flex). It is
possible to explicitly disable this even when flex support this. Use --disable-megaco-reentrant-flex-scanner when configuring the applica-
tion.
DATA TYPES
megaco_ports() = term()
megaco_version() = integer() >= 1
EXPORTS
start() -> {ok, PortOrPorts} | {error, Reason}
Types PortOrPorts = megaco_ports()
Reason = term()
This function is used to start the flex scanner. It locates the library and loads the linked in driver.
On a single core system or if it's a non-reentrant scanner, a single port is created. On a multi-core system with a reentrant scan-
ner, several ports will be created (one for each scheduler).
Note that the process that calls this function must be permanent. If it dies, the port(s) will exit and the driver unload.
stop(PortOrPorts) -> stopped
Types PortOrPorts = megaco_ports()
This function is used to stop the flex scanner. It also unloads the driver.
is_reentrant_enabled() -> Boolean
Types Boolean = boolean()
Is the flex scanner reentrant or not.
is_scanner_port(Port, PortOrPorts) -> Boolean
Types Port = port()
PortOrPorts = megaco_ports()
Boolean = boolean()
Checks if a port is a flex scanner port or not (useful when if a port exits).
scan(Binary, PortOrPorts) -> {ok, Tokens, Version, LatestLine} | {error, Reason, LatestLine}
Types Binary = binary()
PortOrPorts = megaco_ports()
Tokens = list()
Version = megaco_version()
LatestLine = integer()
Reason = term()
Scans a megaco message and generates a token list to be passed on the parser.
