12 lut 2012 · It returns EOF only on "input failure" (EOF, read errors, or encoding errors), and only if the input failure happens before any successful conversion and assignment.
2 gru 2011 · I know it's an EOF problem because when I change the 'for' condition to something like i < 20, it almost works - except it'll read 'D' forever (i.e. with my printf, all the letters will print, but the last letter, 'D' is printed a bunch of times. How do I fix this? Thanks. BTW - writing in C not C++ (but this should work for both anyway, right?)
I'm trying to parse a file with hexadecimal values with each concurrent value being below the other. I'm using fscanf() to parse the file but i keep…
Reaching the end of the string in sscanf() shall be equivalent to encountering end-of-file for fscanf(). If conversion terminates on a conflicting input, the offending input is left unread in the input.
Reaching the end of the string in sscanf () is equivalent to encountering end-of-file for fscanf (). If conversion terminates on a conflicting input, the offending input is left unread in the input. Any trailing white space (including newline characters) is left unread unless matched by a conversion specification.
4 lip 2022 · 1) reads the data from stdin. 2) reads the data from file stream stream. 3) reads the data from null-terminated character string buffer. Reaching the end of the string is equivalent to reaching the end-of-file condition for fscanf.
The value EOF is returned if the end of input is reached before either the first successful conversion or a matching failure occurs. EOF is also returned if a read error occurs, in which case the error indicator for the stream (see ferror(3)) is set, and errno is set to indicate the error.
