curl_getenv(3) libcurl Manual curl_getenv(3) NAME curl_getenv - return value for environment name SYNOPSIS #include <curl/curl.h> char *curl_getenv(const char *name); DESCRIPTION curl_getenv() is a portable wrapper for the getenv() function, meant to emulate its behavior and provide an identical interface for all operat- ing systems libcurl builds on (including win32). You must curl_free(3) the returned string when you are done with it. EXAMPLE char *width = curl_getenv("COLUMNS"); if(width) { /* it was set! */ curl_free(width); } 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(). RETURN VALUE A pointer to a null-terminated string or NULL if it failed to find the specified name. NOTE Under unix operating systems, there is no point in returning an allo- cated memory, although other systems will not work properly if this is not done. The unix implementation thus has to suffer slightly from the drawbacks of other systems.
