Header File

Category

Input/output Routines

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.
