setenv
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);
int unsetenv(const char *name);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
setenv(), unsetenv():
_BSD_SOURCE || _POSIX_C_SOURCE >= 200112L || _XOPEN_SOURCE >= 600
DESCRIPTION
The setenv() function adds the variable name to the environment 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 nonzero; if overwrite is zero, then the value of name is not
changed. This function makes copies of the strings pointed to by name and value (by contrast with putenv(3)).
The unsetenv() function deletes the variable name from the environment. If name does not exist in the environment, then the function suc-
ceeds, and the environment is unchanged.
RETURN VALUE
The setenv() function returns zero on success, or -1 on error, with errno set to indicate the cause of the error.
The unsetenv() function returns zero on success, or -1 on error, with errno set to indicate the cause of the error.
ERRORS
EINVAL name is NULL, points to a string of length 0, or contains an '=' character.
ENOMEM Insufficient memory to add a new variable to the environment.
CONFORMING TO
4.3BSD, POSIX.1-2001.
NOTES
POSIX.1-2001 does not require setenv() or unsetenv() to be reentrant.
Prior to glibc 2.2.2, unsetenv() was prototyped as returning void; more recent glibc versions follow the POSIX.1-2001-compliant prototype
shown in the SYNOPSIS.
BUGS
POSIX.1-2001 specifies that if name contains an '=' character, then setenv() should fail with the error EINVAL; however, versions of glibc
before 2.3.4 allowed an '=' sign in name.
