# PRSeekWhence Specifies how to interpret the `offset` parameter in setting the file pointer associated with the `fd` parameter for the {ref}`PR_Seek` and {ref}`PR_Seek64` functions. ## Syntax ```{code} #include typedef PRSeekWhence { PR_SEEK_SET = 0, PR_SEEK_CUR = 1, PR_SEEK_END = 2 } PRSeekWhence; ``` ### Enumerators The enumeration has the following enumerators: `PR_SEEK_SET` : Sets the file pointer to the value of the `offset` parameter. `PR_SEEK_CUR` : Sets the file pointer to its current location plus the value of the `offset` parameter. `PR_SEEK_END` : Sets the file pointer to the size of the file plus the value of the `offset` parameter.
