Bug #: 54333
Summary: sprinf and fprintf work not always equal
Classification: Unclassified
Product: gcc
Version: 4.6.1
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: c++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: lirex.software@gmail.com
Created attachment 28059
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=28059
the c++ source file
in the following part of the code:
profit_tax_stream = fopen ("test_write.txt","w");
profit_tax_stream2 = fopen ("test2.txt","r");
//fputc(c, profit_tax_stream[0]);
fprintf(profit_tax_stream, "testtest\" test 123");
strcpy(chBuffer,"\0");
//strcat(chBuffer," adsadasda");
fscanf(profit_tax_stream2,"%s", chBuffer);
fprintf(profit_tax_stream,"%s", chBuffer);
//fscanf(profit_tax_stream2, chBuffer);
//fprintf(profit_tax_stream, chBuffer);
//fprintf(profit_tax_stream[0], "<?xml version=\"1.0\" encoding=\"UTF-8\" ?>");
fclose(profit_tax_stream);
fclose(profit_tax_stream2);
fscanf reads a portion of data delimited by space, but only
when I use
fscanf(profit_tax_stream2,"%s", chBuffer);
but it reads nothing at all(I see nothing added to the file opened for write
and also I tried to output the content of chBuffer via Messagebox) when I use
fscanf(profit_tax_stream2, chBuffer);
line of code instead.
The problem is, that the "opposite" function fprintf works in both cases.
