size_t fwrite(
const void *ptr, /* output buffer */
size_t size, /* item size */
size_t nmemb, /* item count */
FILE *stream /* stream pointer */
)
Description
Arguments
Return Value
Error Codes
The fwrite() function writes, from the array pointed to by ptr, up to nmemb
elements whose size is specified by size to the stream pointed to by stream.
The file position indicator for the stream (if defined) is advanced by the number of
characters successfully written. If an error occurs, the resulting value of the file
position indicator for the stream is indeterminate.
ptr Points to the output buffer.
size Specifies the size of each item to write.
nmemb Specifies the number of items to write.
stream Points to an open pREPC+ stream.
This function returns the number of items written. If an error occurs, errno is set.
