StrWriteFmtInternalDescription
Print out a formatted string with rust-style placeholders to given string o.
Warning
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. |
argc | in | Number of arguments. |
Success
Placeholders in fmtstr are replaced by passed arguments.
Failure
Does not return, displays log messages.
