2.3.4 Other Extensions

The Fortran 95 compiler recognizes the following additional intrinsic functions:

`MPI_SIZEOF(` `x``,` `size``,` `error``)` Returns the size in bytes of the machine representation of the given variable, `x`. If `x` is an array, it returns the size of the base element and not the size of the whole array
x	input; variable or array of arbitrary type
`size`	output; integer; size in bytes of `x`
`error`	output; integer; set to an error code if an error detected, zero otherwise

Memory allocation, reallocation, and deallocation functions malloc(), realloc(), and free() are implemented as f95 intrinsics. See 1.4.35 malloc, malloc64, realloc, free: Allocate/Reallocate/Deallocate Memory for details.
