The memory it refers to is malloc()ed why the application must +free() this when the data has completed to serve its purpose. When +.I curl_getenv() +fails to find the specified name, it returns a null pointer. +.SH NOTE +Under unix operating systems, there isn't any point in returning an allocated +memory, although other systems won't work properly if this isn't done. The +unix implementation thus have to suffer slightly from the drawbacks of other +systems. +.SH "SEE ALSO" +.BR getenv "(3C), " +.SH BUGS +Surely there are some, you tell me! + |
