.SH DESCRIPTION
|
|
This function returns a pointer to the first or the next curl_easyoption
|
|
struct, providing an ability to iterate over all known options for
|
|
\fIcurl_easy_setopt(3)\fP in this instance of libcurl.
|
|
|
|
Pass a \fBNULL\fP argument as \fBprev\fP to get the first option returned, or
|
|
pass in the current option to get the next one returned. If there is no more
|
|
option to return, \fIcurl_easy_option_next(3)\fP returns NULL.
|
|
|
|
The options returned by this functions are the ones known to this libcurl and
|
|
information about what argument type they want.
|
|
|
|
If the \fBCURLOT_FLAG_ALIAS\fP bit is set in the flags field, it means the
|
|
name is provided for backwards compatibility as an alias.
|
|
.SH EXAMPLE
