Top Forums Programming How to access a C function from a shell script? Post 302979142 by Don Cragun on Wednesday 10th of August 2016 01:47:36 AM

I fail to see how this thread is fundamentally different from the 1st question in your first thread: How to extract operand size in bits of a C program? nor why you believe that changing from an addition to a multiplication should cause a different answer than what you received in post #2 in that thread??? Is there some reason why you believe the answer I provided there is wrong?

I suppose if you really wanted to you could try to write a C language parser in a shell script to look for every multiplication operation in the C and assembler source files it is asked to process and instead of producing object code emits sizes of the types of the variables or constants being multiplied. And, if what you really want is the highest bit set in the results of each of those multiplications (as in the second question in your first thread), you would not only have to produce runnable object code, but also run them with real data and have your compiler add code to that object code that would print he highest bit set after each multiplication operation found in the source files you processed with your compiler.

I won't say it is impossible to do this, but shell is certainly not the language of choice for a project like this.

curl_global_init(3)						  libcurl Manual					       curl_global_init(3)

NAME
curl_global_init - Global libcurl initialisation SYNOPSIS
#include <curl/curl.h> CURLcode curl_global_init(long flags); DESCRIPTION
This function sets up the program environment that libcurl needs. Think of it as an extension of the library loader. This function must be called at least once within a program (a program is all the code that shares a memory space) before the program calls any other function in libcurl. The environment it sets up is constant for the life of the program and is the same for every program, so multiple calls have the same effect as one call. The flags option is a bit pattern that tells libcurl exactly what features to init, as described below. Set the desired bits by ORing the values together. In normal operation, you must specify CURL_GLOBAL_ALL. Don't use any other value unless you are familiar with it and mean to control internal operations of libcurl. This function is not thread safe. You must not call it when any other thread in the program (i.e. a thread sharing the same memory) is run- ning. This doesn't just mean no other thread that is using libcurl. Because curl_global_init() calls functions of other libraries that are similarly thread unsafe, it could conflict with any other thread that uses these other libraries. See the description in libcurl(3) of global environment requirements for details of how to use this function. FLAGS
CURL_GLOBAL_ALL Initialize everything possible. This sets all known bits. CURL_GLOBAL_SSL Initialize SSL CURL_GLOBAL_WIN32 Initialize the Win32 socket libraries. CURL_GLOBAL_NOTHING Initialise nothing extra. This sets no bit. RETURN VALUE
If this function returns non-zero, something went wrong and you cannot use the other curl functions. SEE ALSO
curl_global_init_mem(3), curl_global_cleanup(3), curl_easy_init(3) libcurl(3) libcurl 7.12 11 May 2004 curl_global_init(3)
