getenv
getenv(3C) Standard C Library Functions getenv(3C)NAME
getenv - return value for environment name
SYNOPSIS
#include <stdlib.h>
char *getenv(const char *name);
DESCRIPTION
The getenv() function searches the environment list (see environ(5)) for a string of the form name=value and, if the string is present,
returns a pointer to the value in the current environment.
RETURN VALUES
If successful, getenv() returns a pointer to the value in the current environment; otherwise, it returns a null pointer.
USAGE
The getenv() function can be safely called from a multithreaded application. Care must be exercised when using both getenv() and
putenv(3C) in a multithreaded application. These functions examine and modify the environment list, which is shared by all threads in an
application. The system prevents the list from being accessed simultaneously by two different threads. It does not, however, prevent two
threads from successively accessing the environment list using getenv() or putenv(3C).
