Sorry for the inconvenience. If you happen to know the Solaris equivalent of setenv(3), please let me know so I can fix it correctly.

It looks like Solaris supports getenv() and putenv(). Man pages follow:

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 mul- tithreaded application. Care must be exercised when using both getenv() and putenv(3C) in a multithreaded applica- tion. 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 simultane- ously by two different threads. It does not, however, prevent two threads from successively accessing the environ- ment list using getenv() or putenv(3C).

NAME putenv - change or add value to environment

SYNOPSIS #include <stdlib.h>

int putenv(char *string);

DESCRIPTION The putenv() function makes the value of the environment variable name equal to value by altering an existing vari- able or creating a new one. In either case, the string pointed to by string becomes part of the environment, so altering the string will change the environment.

The string argument points to a string of the form name=value. The space used by string is no longer used once a new string-defining name is passed to putenv().

The putenv() function uses malloc(3C) to enlarge the environment.

After putenv() is called, environment variables are not in alphabetical order.

RETURN VALUES The putenv() functions returns a non-zero value if it was unable to obtain enough space using malloc(3C) for an expanded environment. Otherwise, 0 is returned.

ERRORS The putenv() function may fail if:

ENOMEM Insufficient memory was available.

USAGE The putenv() function can be safely called from mul- tithreaded programs. Caution must be exercised when using this function and getenv(3C) in multithreaded programs. These functions examine and modify the environment list, which is shared by all threads in a program. 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 putenv() or getenv().

WARNINGS The string argument should not be an automatic variable. It should be declared static if it is declared within a func- tion because it cannot be automatically declared. A poten- tial error is to call putenv() with a pointer to an automatic variable as the argument and to then exit the cal- ling function while string is still part of the environment.
