22 | * Purpose:
|
---|
23 | * A merge of Bjorn Reese's format() function and Daniel's dsprintf()
|
---|
24 | * 1.0. A full blooded printf() clone with full support for <num>$
|
---|
25 | * everywhere (parameters, widths and precisions) including variabled
|
---|
26 | * sized parameters (like doubles, long longs, long doubles and even
|
---|
27 | * void * in 64-bit architectures).
|
---|
28 | *
|
---|
29 | * Current restrictions:
|
---|
30 | * - Max 128 parameters
|
---|
31 | * - No 'long double' support.
|
---|
32 | *
|
---|
33 | * If you ever want truly portable and good *printf() clones, the project that
|
---|
34 | * took on from here is named 'Trio' and you find more details on the trio web
|
---|
35 | * page at https://daniel.haxx.se/trio/
