| | | | | | The getenv(3) and unsetenv(3) functions already support this. This will make it easier to emulate the glibc clearenv() function in ports. Based on a diff from and OK jca@

| | | | | | C standard are all weak. Apply __{BEGIN,END}_HIDDEN_DECLS to gdtoa{,imp}.h, hiding the arch-specific __strtorx, __ULtox_D2A, __strtorQ, __ULtoQ_D2A symbols.
* using reallocarray() gives us multiplicative integer overflow checkingderaadt2014-10-081-3/+3
| | | | | | | | | | in case something wants to create massive amounts of environment, like a bit more than 1/4 of a 32-bit address space. unrealistic -- but why audit one code path, and not treat others the same? then you have to re-engage everytime you see the code. read the news, that isn't what developers do. At least if the code paths look the same, there is hope, because they are easier to verify for correctness. developers need to give other developers a chance to want to care.

| | | | | Someone may have passed a read-only string to putenv() (I'm looking at you cron!).
* Make putenv(), setenv() and unsetenv() standards compliant. Themillert2009-06-031-11/+68
| | | | | | standard explicitly disallows passing setenv a name with a '=' in it but historic BSD behavior is to allow this but to ignore the '=' and anything after it.
