| .TH curl_getenv 3 "30 April 2004" "libcurl 7.12" "libcurl Manual" |
| .SH NAME |
| curl_getenv - return value for environment name |
| .SH SYNOPSIS |
| .B #include <curl/curl.h> |
| .sp |
| .BI "char *curl_getenv(const char *" name ");" |
| .ad |
| .SH DESCRIPTION |
| curl_getenv() is a portable wrapper for the getenv() function, meant to |
| emulate its behavior and provide an identical interface for all operating |
| systems libcurl builds on (including win32). |
| |
| You must \fIcurl_free(3)\fP the returned string when you're done with it. |
| .SH AVAILABILITY |
| This function will be removed from the public libcurl API in a near future. It |
| will instead be made "available" by source code access only, and then as |
| curlx_getenv(). |
| .SH RETURN VALUE |
| A pointer to a null-terminated string or NULL if it failed to find the |
| specified name. |
| .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), " |
