fscanf problem

[jespersh]

I have a problem concerning fscanf: I which to save an array of
structures to a file, and to boil things down let's say I save the
'type' member (which is a char) as:

void save(struct part *ptr, const char *file, int npart){
FILE *fout;
int n;

fout = fopen(file, "w");
/* some check */

for ( n=0; n<npart; n++ )
fprintf(fout, "%c\n", ptr[n].type);

fclose(fout);
}

(Here the array is 'npart' long.) Now, I wish to load the data through
the following function:

void load(struct part *ptr, const char *file, int npart){
FILE *fin;
int n;

fin = fopen(file, "r");
/* some check */

for ( n=0; n<npart; n++ )
fscanf(fin, "%c", &ptr[n].type);

fclose(fin);
}

This will lead to very strange behavior. As I understand fscanf skips
\n, space etc, but it seems from the output as if it includes the
newline character twice.

Am I missing the definition of fscanf?

Hrmmphh... I am not missing the definition... I meant "misunderstanding"

There are two exceptions to fscanf skipping leading whitespace:
- if the format element is %c
- if the format element is %[
