I did not see your previous postings but it seems that you should consider
reading a good book about C language. texte in your example is an address
of a static array of char and it is not changed: texte!=NULL is always true
(you are able to change a variable texte but it is not a good idea). You
could want to write *texte='\0' if your file is "\n\0" terminated. Although,
it is really  better to use feof(FILE *) to check if the end of file is
encounted.

Also, there exists strncmp(const char *,const char *,size_t) library
function. Multiple if's are substituted by
strncmp(texte,"[drivers32]",sizeof("[drivers32]")-1) using it.
