Format specifiers for the reading functions sscanf and fscanf differ from the formats for the writing functions sprintf and fprintf. The reading functions do not support a precision field. The width field specifies a minimum for writing, but a maximum for reading. If you specify an invalid formatting operator or special character, then fprintf prints all text up to the invalid operator or character and discards the rest.

In formatSpec , hexadecimal numbers must be in the range [0 7F] and octal numbers must be in the range [0 ]. If fileID has a constant value of 1 or 2 and extrinsic calls are not possible, the code generator produces a C printf call. Extrinsic calls are not possible when extrinsic calls are disabled or when fprintf is called inside a parfor loop. The fprintf call is inside a parfor loop. Using subtypes to print a floating-point number as its octal, decimal, or hexadecimal value.

Input argument types must match their format types. For code generation, first cast n to a signed integer type such as int8. When you call fprintf with an integer format specifier, the type of the integer argument must be a type that the target hardware can represent as a native C type. This function fully supports thread-based environments. Choose a web site to get translated content where available and see local events and offers.
