int i;

jmp_buf (env)

i=setjmp(env)

longjmp(env,i);
malloc
Allocates space for an object whose size is specified by size .
The existing implementation of malloc() depends on the heap area being located from
the bottom of the heap (referred to by the symbol __heapbot) to the top of the stack (SP).
Care must be taken to avoid holes in this memory range. Otherwise, the
malloc() func-
tion might not be able to allocate a valid memory object.
Synopsis
#include

void *malloc(size_t size);
Returns
A pointer to the start (lowest byte address) of the allocated space. If the space cannot be
allocated, or if size is zero, the
malloc function returns a null pointer.
Example
char *buf;

buf=(char *) malloc(40*sizeof(char));

if(buf !=NULL)

/*success*/

else

/*fail*/
memchr
Locates the first occurrence of c (converted to an unsigned char ) in the initial n charac-
ters of the object pointed to by s.
Synopsis
#include

void *memchr(void *s, int c, size_t n);
