StrWriteFmtInternal
StrWriteFmtInternal
Description
Print out a formatted string with rust-style placeholders to given string o.
Directly passing literals like
1337 is not supported, especially const char* literals. For constants like integers, booleans, you can use LVAL(r-value) to convert an l-value to an r-value an then use in FMT like LVAL(false)
Parameters
| Name | Direction | Description |
|---|---|---|
o |
out | Contents appended to this string. |
fmtstr |
in | Format string with placeholders. |
argv |
in | Arguments that placeholders will be replaced with. |
