int fprintf( FILE *fp, const char *format [, arg1, arg2, ...] )
- prototype in stdio.h
- returns number of bytes it attempted to write regardless of
success. To check for a successful fprintf call on a buffered
stream, use fflush which returns accurate error information.
- using printf or any of the stdio functions results in a default
allocation of 512 bytes for the I/O buffer and the inclusion of
the standard memory allocation functions
- see printf() and PRINTF SPEC
