putenv

putenv(3C)																putenv(3C)

NAME

       putenv() - change or add value to environment

SYNOPSIS

DESCRIPTION

       string  points to a string of the form name=value.  makes the value of the environment variable name equal to value by altering an existing
       variable or creating a new one.	In either case, the string pointed to by string becomes part of the environment, so  altering  the  string
       changes the environment.  The space used by string is no longer used once a new string-defining name is passed to

EXTERNAL INFLUENCES

   Locale
       The category determines the interpretation of characters in string as single- and/or multi-byte characters.

   International Code Set Support
       Single- and multi-byte character code sets are supported.

DIAGNOSTICS

       returns non-zero if it was unable to obtain enough space via for an expanded environment, or if an invalid multibyte character sequence was
       encountered in the string argument; otherwise it returns zero.

ERRORS

       fails under the following conditions:

	      [ENOMEM]	     There is insufficient space to expand the environment.

	      [EILSEQ]	     An invalid multibyte character sequence was encountered in the string argument.

WARNINGS

       manipulates the environment pointed to by environ, and can be used in conjunction with However, envp (the third argument to  main)  is  not
       changed.

       This routine uses to enlarge the environment (see malloc(3C)).

       After is called, environmental variables are not in alphabetical order.

       A  potential  error is to call with an automatic variable as the argument, then exit the calling function while string is still part of the
       environment.
