SETENV(3)           Linux Programmer's Manual           SETENV(3)
+

+
+
NAME
+
       setenv - change or add an environment variable
+
+
SYNOPSIS
+
       #include <stdlib.h>
+
+       int setenv(const char *name, const char *value, int overwrite);
+
+       void unsetenv(const char *name);
+
+
DESCRIPTION
+
       The  setenv() function adds the variable name to the envi-
+       ronment with the value value, if  name  does  not  already
+       exist.   If  name  does exist in the environment, then its
+       value is changed to value if  overwrite  is  non-zero;  if
+       overwrite  is zero, then the value of name is not changed.
+
+       The unsetenv() function deletes the variable name from the
+       environment.
+
+
RETURN VALUE
+
       The  setenv()  function  returns zero on success, or -1 if
+       there was insufficient space in the environment.
