Hello ,

I will have two questions . First I havent got a enough information about the funcitons : malloc,calloc,realloc. Can anyone show me a direction to a source or can anyone directly explain their jobs detailed?
Secondly , does the vary the sscanf function returns depends on the how many variable it used? By variable I mean the variables that we save the varies that we took from the string we put into the first argument of sscanf function.

I hope I made my questions clear. I will be glad if you help. Thank you..

(for example sscanf(s,"%d",&a)==1 ??? )
