extern |
Adds the assignments from the array of pointers to the environment string. The array must be terminated by a NULL
pointer, just the same as the standard environ
array.
References envstr_put().
|
extern |
Adds the string-based list of assignments to the environment string. Each individual assignment in the list must be ASCII NUL terminated, and the final assignment must be followed by two ASCII NULs.
References envstr_put().

extern |
Get the value of an assignment from an environment string.
References envstr_find().

extern |
Make a environ
compatable array of pointers to the environment string.

extern |
Put an assignment, in NAME=value
format, into the environment string.

extern |
Set the named variable to the given value in the environment string.
