MBKREALLOC(3) MBK UTILITY FUNCTIONS MBKREALLOC(3) NAME mbkrealloc - mbk memory reallocator SYNOPSIS #include "mut.h" void *mbkrealloc(pt, bytes) void *pt; unsigned int bytes; PARAMETERS pt Pointer to an already allocated area, allocated us- ing mbkallocP bytes Number of memory bytes to be contiguously allocated DESCRIPTION mbkrealloc returns a block of bytes length, for any purpose. It in- creases or decreases the size of the area, and return a pointer to the new block. It is now a day only an encapsulation of the system realloc function, but may evolve to a special allocator in the future. Its use is strongly encouraged. Remark : a global variable, long mbkrealloc_stat, updates the number of allocated bytes, and may be accessed by anyone to see the amount of allocated memory. RETURN VALUE mbkrealloc returns a pointer to a bytes long block. ERROR "*** mbk error *** mbkrealloc impossible : not enough memory" System break can't be moved anymore, no more memory can be re- trieved from the system. EXAMPLE #include "mut.h" char *concatstring(t, s); { t = (char *)mbkrealloc(strlen(t) + strlen(s) + 1); strcat(t, s); return t; } SEE ALSO mbk(1), mbkalloc(3), mbkfree(3).
