Hi,
I want a command in unix shell script which will exit my whole program, not only from the function it's using. For e.g:
$1 == "m_who" && $4 == "Extrnl Vendor" {
print "You don have access"
exit (0);
}
If this error is showing on the screen, then nothing should not... (9 Replies)
Apart from writing debug and statements in constructors is there any way by which we can trace the function call stack at any depth?
The issue that we always face is that when program crashes (Web Server running on Linux) we have no idea where it crashes and we have to do the hard way of... (1 Reply)
Hello All,
Is there any way to find a function name in a program file using perl.
for example, there is a file called Test.C in that
.

void function1(..)
{
<some code>
}
int function2(..)
{

I have a program which has 7-8 threads, and lots of shared variables; these variables (and also they may not the primitive type, they may be enum or struct ), then they may read/write by different threads at the same time.
Now, my design is like this,

I am looking to create some ksh93 extensions using the custom builtin feature.
I can successfully create a builtin function, load it using the builtin -f command and get an output. However, I want to get/set values of KSH variables from within my built-in.
For example, lets say I am creating... (2 Replies)
Why do shell builtins like echo and pwd have binaries in /bin? When I do which pwd, I get the one in /bin. that means that I am not using the builtin version? What determines which one gets used? Is the which command a definitive way to determine what is being run when I enter pwd? (16 Replies)
We have a program source C and is required to indicate how many times each function is called from the C program. also print the line number where there is a call.
I've tried something like this:

then
echo $i is not a C file.

Hi !
It is a general question.
When an awk script looks like:
#! bin/awk
function example(i){

{
example(1) #the function uses input_1 and return output_a
}

example(2) #the function uses previous output_a as an input and returns... (15 Replies)
Not sure if this is the right forum but I have collated a listing of shell and bash builtins.
Builtins is a loose word and may include the '/bin' drawer/folder/directory but NOT any
others in the path list.
In the case of my Macbook Pro, OSX 10.7.5 the enabled internals is also listed...

I work at a company that uses a program written in AWK to track various data and prepare reports.

builtin(1) User Commands builtin(1)NAME
builtin - ksh93 built-in function to add, delete, or display shell built-ins
SYNOPSIS
builtin [-ds] [-f lib] [pathname ...]
DESCRIPTION
The ksh93 builtin command adds, deletes, or displays built-in commands in the current shell environment. A built-in command executes in the
current shell process and can have side effects in the current shell. On most systems, the invocation time for built-in commands is one or
two orders of magnitude less than commands that create a separate process.
For each pathname specified, the basename of the pathname determines the name of the built-in. For each basename, the shell looks for a C
level function in the current shell whose name is determined by pre-pending b_ to the built-in name. If pathname contains a forward slash
(/), the built-in is bound to pathname. A built-in bound to a pathname is only executed if pathname is the first executable found during a
path search. Otherwise, built-ins are found prior to performing the path search.
If pathname is not specified, builtin displays the current list of built-ins, or just the special built-ins if the -s option is specified,
on standard output. The full pathname for built-ins that are bound to pathnames are displayed.
Libraries containing built-ins can be specified with the -f option. If the library contains a function named lib_init(), this function is
invoked with argument 0 when the library is loaded. The lib_init() function can load built-ins by invoking an appropriate C level function.
In this case there is no restriction on the C level function name.
The C level function is invoked with three arguments. The first two are the same as main() and the third one is a pointer.
The ksh93 builtin command cannot be invoked from a restricted shell.
OPTIONS
The following options are supported:
-d Delete each of the specified built-ins. Special built-ins cannot be deleted.
-f lib On systems with dynamic linking, load and search for built-ins in the shared library, lib.
Libraries are searched for in $PATH and system dependent library directories. The system dependent shared library prefix or suf-
fix can be omitted. Once a library is loaded, its symbols become available for the current and subsequent invocations of builtin.
Multiple libraries can be specified with separate invocations of builtin. Libraries are searched in the reverse order in which
they are specified.
-s Display only the special built-ins.
OPERANDS
The following operands are supported:
pathname Specifies the pathname. The basename of the pathname determines the name of the built-in.
EXIT STATUS
The following exit values are returned:
0 Successful completion.
>0 An error occurred.
EXAMPLES
Example 1 Loading a builtin Command
The following example loads a builtin command mycmd from the library libfoo.so:
example% builtin -f foo mycmd
