Defined in header
Writes up to
count objects from the given array
buffer to the output stream
stream as if by reinterepreting each object as an array of unsigned char and calling std::fputc
size times for each object to write those unsigned chars into
stream, in order. The file position indicator for the stream is advanced by the number of characters written.
If the objects are not
TriviallyCopyable, the behavior is undefined.
If an error occurs, the resulting value of the file position indicator for the stream is indeterminate.
|buffer||-||pointer to the first object object in the array to be written|
|size||-||size of each object|
|count||-||the number of the objects to be written|
Number of objects written successfully, which may be less than
count if an error occurred.
count is zero,
fwrite returns zero and performs no other action.
