Description
Assembles a formatted string using a format string and an array of arguments.
This function formats the series of arguments in the specified open (untyped) array.
Result
represents the result of the operation.
Format
is the format string that determines how to generate Result
. For information on the format strings, see Format strings.
Args
is an array of arguments that replaces the format specifiers in Format.
Note:
Args_Size
specifies the index of the last element ofArgs
(one less than the number of elements).
The first form of FmtStr is not thread-safe, because it uses localization information contained in global variables. The second form of FmtStr, which is thread-safe, refers to localization information contained in the AFormatSettings
parameter. Before calling the thread-safe form of FmtStr, you must populate AFormatSettings
with localization information. To populate AFormatSettings
with a set of default locale values, call TFormatSettings.Create.
