NAME
setenviron - set environment value
SYNOPSIS
#include <ast.h> char* setenviron(const char* key);
DESCRIPTION
setenviron controls environment name=value pairs. setenviron("name=value") adds name to the environment and returns a pointer to a strdup(3) copy of name=value. setenviron("name") removes name from the environment and returns the empty string. setenviron(0) reserves a few slots in an internal array and is usually called by a parent process that expects many children. 0 is returned on error. setenviron preserves the ksh(1) convention of _ as the first environment variable name.
