Efree()

void Efree

(

void *

ptr

)

Definition at line 45 of file emalloc.cpp.

void* Emalloc

(

int

Size

)

This routine attempts to allocate the specified number of bytes. If the memory can be allocated, a pointer to the memory is returned. If the memory cannot be allocated, or if the allocation request is negative or zero, an error is trapped.

Pointer to allocated memory.
