Pointer to the process's environment variables
Synopsis:
#include <unistd.h>
extern char ** environ;
Library:
libc
Use the -l c option to qcc to link against this library. This library is usually included automatically.
Description:
When a process begins, an array of strings called the environment is made available. This array is pointed to by the external variable environ. The strings in the array have the form:
variable=value
and are terminated by a NULL pointer.
Classification:
Caveats:
Don't modify environ directly; use clearenv(), getenv(), putenv(), searchenv(), setenv(), and unsetenv().
Changes to the environment affect all threads in a multithreaded process.
