Good grief so this should be easy. Passing an array as an argument to a function. Here is the sample code:
Obviously, it prints
data1
bat
bar
And what I want is:
data1
bat
data2
I would take
data1
bat bar baz
data2
As that would still be workable. I'm simply trying to stuff the array into the second argument somehow that isn't nasty and hard to understand. Obviously in the real example, there are multiple arrays being passed, so playing with the tokens isn't a great solution for me.
Passing a array to a function, a basic feature in modern language, seems to be only possible in KSH. Not in BASH. Depite all my efforts I couldn't come to a solution. See the following examples:
It works perfectly in KSH:
#!/usr/bin/ksh
function print_array {

Hi
I am passing or want to pass value of a char array, so that even thoug the called routine is changing the values the calling function should not see the values changed, meaning only copy should be passed

Hi,
I'm trying to write a function that reassigns an array to
another local array but the method used in reassigning
the array reformats the contents of the array which is
what I am trying to prevent.
The method used to load a file into an array works as
expected and the entire array is... (4 Replies)
Hi.
I have a problem with passing two dimensional array to a function.
First, let me show my code to explain what i am going to do:

I'm trying to use the following command:

It also appears that awk scripts... (3 Replies)
Hi,
I'm trying to write a bash script that takes a file and passes each line from the file into an array with elements separated by column.

GLIB-GENMARSHAL(1) [FIXME: manual] GLIB-GENMARSHAL(1)NAME
glib-genmarshal - C code marshaller generation utility for GLib closures
SYNOPSIS
glib-genmarshal [options...] [files...]
DESCRIPTION
glib-genmarshal is a small utility that generates C code marshallers for callback functions of the GClosure mechanism in the GObject
sublibrary of GLib. The marshaller functions have a standard signature, they get passed in the invoking closure, an array of value
structures holding the callback function parameters and a value structure for the return value of the callback. The marshaller is then
responsible to call the respective C code function of the closure with all the parameters on the stack and to collect its return value.
INVOCATION
glib-genmarshal takes a list of marshallers to generate as input. The marshaller list is either read from standard input or from files
passed as additional arguments on the command line.
Options
--header
Generate header file contents of the marshallers.
--body
Generate C code file contents of the marshallers.
--prefix=string, --prefix string
Specify marshaller prefix. The default prefix is `g_cclosure_marshal'.
--skip-source
Skip source location remarks in generated comments.
--nostdinc
Do not use the standard marshallers of the GObject library, and skip gmarshal.h include directive in generated header files.
--g-fatal-warnings
Make warnings fatal, that is, exit immediately once a warning occurs.
-h, --help
Print brief help and exit.
-v, --version
Print version and exit.
Marshaller list format
The marshaller lists are processed line by line, a line can contain a comment in the form of
# this is a comment
or a marshaller specification of the form
RTYPE:PTYPE
RTYPE:PTYPE,PTYPE
RTYPE:PTYPE,PTYPE,PTYPE
(up to 16 PTYPEs may be present).
The RTYPE part specifies the callback's return type and the PTYPEs right to the colon specify the callback's parameter list, except for the
first and the last arguments which are always pointers.
Parameter types
Currently, the following types are supported:
VOID
indicates no return type, or no extra parameters. If VOID is used as the parameter list, no additional parameters may be present.
BOOLEAN
for boolean types (gboolean)
CHAR
for signed char types (gchar)
UCHAR
for unsigned char types (guchar)
INT
for signed integer types (gint)
UINT
for unsigned integer types (guint)
LONG
for signed long integer types (glong)
ULONG
for unsigned long integer types (gulong)
INT64
for signed 64bit integer types (gint64)
UINT64
for unsigned 64bit integer types (guint64)
ENUM
for enumeration types (gint)
FLAGS
for flag enumeration types (guint)
FLOAT
for single-precision float types (gfloat)
DOUBLE
for double-precision float types (gdouble)
STRING
for string types (gchar*)
BOXED
for boxed (anonymous but reference counted) types (GBoxed*)
PARAM
for GParamSpec or derived types (GParamSpec*)
POINTER
for anonymous pointer types (gpointer)
OBJECT
for GObject or derived types (GObject*)
NONE
deprecated alias for VOID
BOOL
deprecated alias for BOOLEAN
EXAMPLE
To generate marshallers for the following callback functions:
void foo (gpointer data1,
gpointer data2);
void bar (gpointer data1,
gint param1,
gpointer data2);
gfloat baz (gpointer data1,
gboolean param1,
guchar param2,
gpointer data2);
The marshaller list has to look like this:
VOID:VOID
VOID:INT
FLOAT:BOOLEAN,UCHAR
The generated marshallers have the arguments encoded in their function name. For this particular list, they are
g_cclosure_marshal_VOID__VOID(),
g_cclosure_marshal_VOID__INT(),
g_cclosure_marshal_FLOAT__BOOLEAN_UCHAR().
They can be used directly for GClosures or be passed in as the GSignalCMarshaller c_marshaller; argument upon creation of signals:
GClosure *cc_foo, *cc_bar, *cc_baz;
cc_foo = g_cclosure_new (NULL, foo, NULL);
g_closure_set_marshal (cc_foo, g_cclosure_marshal_VOID__VOID);
cc_bar = g_cclosure_new (NULL, bar, NULL);
g_closure_set_marshal (cc_bar, g_cclosure_marshal_VOID__INT);
cc_baz = g_cclosure_new (NULL, baz, NULL);
g_closure_set_marshal (cc_baz, g_cclosure_marshal_FLOAT__BOOLEAN_UCHAR);
