It +will instead be made "available" by source code access only, and then as +curlx_getenv(). +.SH RETURN VALUE +If successful, curl_getenv() returns a pointer to the value of the specified +environment. The memory it refers to is malloc()ed so the application must +free() this when the data is no longer needed. When \fIcurl_getenv(3)\fP 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 has to suffer slightly from the drawbacks of other +systems. +.SH "SEE ALSO" +.BR getenv "(3C), " |
