Prototype 

int fsetpos(FILE *stream, const fpos_t *pos); 

Description 

Positions the file pointer of a stream. 

fsetpos sets the file pointer associated with stream to a new position. The new position is the value obtained by a previous call to fgetpos on that stream. It also clears the end-of-file indicator on the file that stream points to and undoes any effects of ungetc on that file. After a call to fsetpos the next operation on the file can be input or output. 

Return Value 

On success fsetpos returns 0.  

On failure it returns a nonzero value and also sets the global variable errno to a nonzero value.
