NAME
curl_getenv - return value for environment nameDESCRIPTION
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).EXAMPLE
int main(void)
{
char *width = curl_getenv("COLUMNS");
if(width) {
/* it was set! */
curl_free(width);
}
}
AVAILABILITY
AlwaysRETURN 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 allocated memory, although other systems does not work properly if this is not done. The unix implementation thus suffers slightly from the drawbacks of other systems.SEE ALSO
