= sprintf =

== Syntax ==
:{{int sprintf (char * str, const char * format, ... )}}

== Arguments ==
:'''buffer'''
::A pointer to the string buffer where the result will be stored
:'''format'''
::Specifies the format of the resulting string, including types of the variables to be included in the string.

== Return ==
:The number of characters written, not including the terminating null character, or -1 if an error occurred.

== Description ==
:sprintf "prints" a formatted string, except instead of printing it to a terminal console, it stores the result in a string variable.  The formatting uses the printf-style formatting common to the C language.

== Comments ==
:Wherever possible, you should use ((snprintf)) instead.  sprintf can have potential buffer overruns (crashes) depending how it is used - snprinf prevents the overruns.

== Example ==
<code>
int version = 1;
strcpy(str0, "Plug-In Name");
strcpy(str1, "Company Name");
sprintf(str2, "You are running %s made by %s, version %d", str0, str1, version);
printf(str2);
</code>

== See Also ==
:((formatString)), ((printf)), ((snprintf))
