free

Frees memory from malloc().

Synopsis

void free( void *p )

Description

The procedure frees a memory block that was allocated by a call to malloc(). It is identical to the free() procedure in standard C library. The freed memory is automatically returned to the memory list from which it was allocated.

Note: You should only use malloc() and free() when porting existing C programs to Portfolio. If you are writing programs specifically for Portfolio, use AllocMem() and FreeMem(), which allow you to specify the type of memory to allocate, such as VRAM or memory that begins on a page boundary.

Arguments

p
A pointer to the memory to be freed. This pointer may be NULL, in which case this function just returns.

Implementation

Convenience call implemented in clib.lib V20.

Notes

You can enable memory debugging in your application by compiling your entire project with the MEMDEBUG value defined on the compiler's command-line. Refer to the CreateMemDebug() function for more details.

Caveats

Trusts that p is a result of a previous malloc() call.
