Saving a vector to a file
Another C++ question, please do notify me if this forum is C-only!
I'm having a vector...
vector<Person> x;
... with a class I've defined (Person).
I have several elements in this vector and I would like to save it to a file (binary (?)). And later on open up this file to retrieve the elements in the vector.
Any suggestions on how to accomplish this?

NAME
mlib_VectorMag_U8C, mlib_VectorMag_S8C, mlib_VectorMag_S16C, mlib_VectorMag_S32C - vector complex magnitude
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_VectorMag_U8C(mlib_d64 *m, const mlib_u8 *x, mlib_s32 n);
mlib_status mlib_VectorMag_S8C(mlib_d64 *m, const mlib_s8 *x, mlib_s32 n);
mlib_status mlib_VectorMag_S16C(mlib_d64 *m, const mlib_s16 *x, mlib_s32 n);
mlib_status mlib_VectorMag_S32C(mlib_d64 *m, const mlib_s32 *x, mlib_s32 n);
DESCRIPTION
Each of these functions computes the magnitude vector of the complex input vector.
The following equation is used:
m[i] = (x[2*i]**2 + x[2*i + 1]**2)**0.5
where i = 0, 1, ..., (n - 1).
PARAMETERS
Each of the functions takes the following arguments:
m Pointer to the destination magnitude vector.
x Pointer to the source vector
n Number of elements in the vector.
RETURN VALUES
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
