_smalloc()

Allocate memory in blocks

Synopsis:

#include <malloc.h>

void* _smalloc( size_t size );

Arguments:

size
The size of the block to allocate, in bytes.

Library:

libc

Use the -l c option to qcc to link against this library. This library is usually included automatically.

This function is in libc.a, but not in libc.so (in order to save space).

Description:

The _smalloc() function allocates space for an object of size bytes. Nothing is allocated when the size argument has a value of zero.

This function allocates memory in blocks of _amblksiz bytes; _amblksiz is a global variable defined in <stdlib.h>.

You must use _sfree() to deallocate the memory allocated by _smalloc().

Returns:

A pointer to the start of the allocated memory, or NULL if there's insufficient memory available, or if the requested size is zero.
