Source Code Functions Apps Might Use
====================================
The libcurl source code offers a few functions by source only. They are not
part of the official libcurl API, but the source files might be useful for
others so apps can optionally compile/build with these sources to gain
additional functions.
We provide them through a single header file for easy access for apps:
"curlx.h"
curlx_strtoofft()
A macro that converts a string containing a number to a curl_off_t number.
This might use the curlx_strtoll() function which is provided as source
code in strtoofft.c. Note that the function is only provided if no
strtoll() (or equivalent) function exist on your platform. If curl_off_t
is only a 32 bit number on your platform, this macro uses strtol().
curlx_tvnow()
returns a struct timeval for the current time.
curlx_tvdiff()
returns the difference between two timeval structs, in number of
milliseconds.
curlx_tvdiff_secs()
returns the same as curlx_tvdiff but with full usec resolution (as a
double)
FUTURE
======
Several functions will be removed from the public curl_ name space in a
future libcurl release. They will then only become available as curlx_
functions instead. To make the transition easier, we already today provide
these functions with the curlx_ prefix to allow sources to get built properly
with the new function names. The functions this concerns are:
curlx_getenv
curlx_strequal
curlx_strnequal
curlx_mvsnprintf
curlx_msnprintf
curlx_maprintf
curlx_mvaprintf
curlx_msprintf
curlx_mprintf
curlx_mfprintf
curlx_mvsprintf
curlx_mvprintf
curlx_mvfprintf
