Question

I am trying to port an application from Windows to Linux. In Windows I have a
GetEnvironmentStrings() function in windows.h which provides me the environment variables and their values in the current process in
the form NAME=VALUE.

Is there an equivalent Linux function call for this? I need a C function.
How can this be achieved on Linux?

Answer 1

You can access the environment variables through the variable extern char **environ;.

The value of an environment variable is a string of characters. For a C-language program, an array of strings called the environment shall be made available when a process begins. The array is pointed to by the external variable environ, which is defined as:

extern char **environ;

These strings have the form name=value.
