setenviron - set environment value .EX #include <ast.h> char* setenviron(const char* key); .L setenviron controls environment name=value pairs. .L setenviron("name=value") adds name to the environment and returns a pointer to a strdup (3) copy of name=value . .L setenviron("name") removes name from the environment and returns the empty string. .L 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. .L setenviron preserves the ksh (1) convention of .L _ as the first environment variable name. env(1), exec(2) POSIX will eventually settle on an interface. It has already picked a few of the names we did in .2 drafts. This is about the third name change for ours.
