.TH ALLOC 3 .CT 2 mem_man .SH NAME alloc, balloc, bfree, gcalloc, gcfree \- allocate memory .SH SYNOPSIS .B #include <jerq.h> .PP .B char *alloc(nbytes) .B unsigned nbytes; .PP .B Bitmap *balloc(r) .B Rectangle r; .PP .B void bfree(b) .B Bitmap *b; .PP .B char *gcalloc(nbytes, where) .B unsigned long nbytes; .B char **where; .PP .B void gcfree(s) .B char *s; .SH DESCRIPTION .I Alloc is equivalent to the standard C function .IR calloc ; see .IR malloc (3). It returns a pointer to a block of .I nbytes contiguous bytes of storage, or 0 if unavailable. The storage is aligned on 4-byte boundaries and is cleared to zeros. .PP .I Balloc returns a pointer to a Bitmap large enough to contain the Rectangle .IR r , or 0 for failure. The coordinate system inside the Bitmap is set by .IR r : the .B origin and .B corner of the Bitmap are those of .IR r . .I Bfree frees the storage associated with a Bitmap allocated by .IR balloc . .PP .I Gcalloc is also equivalent to the standard C function .IR calloc. It returns a pointer to a block of .I nbytes contiguous bytes of storage, or 0 if unavailable. The storage is initialized to zeros. .I Where is a pointer to the user's data where the location of the block is to be saved. The return value of .I gcalloc is stored in .IR *where . .I Gcfree is equivalent to .IR free . .IR p . .SH SEE ALSO .IR types (5), .IR malloc (3)
