Function Setbuf ()() in C

This guide covers function setbuf ()() in c with practical context and easy-to-follow details. Use it to understand the subject and apply the information confidently.

Declare Setbuf ()() Function in C

Below is the declaration for the setbuf () function in C:

 void setbuf ( FILE * stream , char * buffer ) 

Parameters

Stream - This is the pointer to a FILE object that identifies the opened stream.

Buffer - This is the buffer that has been allocated. It should be at least BUFSIZ bytes in length, which is a macro constant to be used as the length of this array.

Returns the value

This function does not return any values.

For example

The following program C illustrates the usage of the setbuf () function in C:

 #include int main () { char buf [ BUFSIZ ]; setbuf ( stdout , buf ); puts ( "Hoc C co ban tai QTM !!!" ); fflush ( stdout ); return ( 0 ); } 

Compile and run the above program to produce the following results. Here the program sends output to STDOUT just before it exits, otherwise it continues to buffer output. You can also use the fflush () function to flush (delete or move to the periphery) to see the result.
