Syntaks:

grå kode
int sprintf(char *str, const char *string,...);>

Vend tilbage:



If successful, it returns the total number of characters written excluding null-character appended in the string, in case of failure a negative number is returned .>

sprintf står for String print. I stedet for at udskrive på konsollen gemmer den output på char buffer, som er specificeret i sprintf.

C
