MALLOC(3F)MALLOC(3F)NAME
malloc, malloc64 - allocate memory and return the address
SYNOPSIS
INTEGER*4 function malloc(nsize)
INTEGER*4 nsize
in 32-bit environments
INTEGER*8 function malloc(nsize)
INTEGER*4 nsize
in 64-bit environments (SPARC only)
INTEGER*8 function malloc64(nsize)
INTEGER*8 nsize
in all environments (SPARC only)
DESCRIPTION
The function MALLOC(NSIZE) allocates an area of memory, and returns the
address of the start of that area. The argument to the function is an
integer that specifies the amount of memory to be allocated, in bytes.
If successful, it returns a pointer to the first element of the region;
otherwise, it returns an integer 0.
Typically, the variable receiving the result from MALLOC or MALLOC64 is
declared POINTER.
The region of memory is not initialized in any way — assume it is ran‐
dom bits.
When compiled to run in a 64-bit environment, MALLOC takes an INTEGER*4
argument and returns an INTEGER*8 value. Otherwise, it returns a
32-bit INTEGER*4 value
The function MALLOC64 takes an INTEGER*8 argument and always returns an
INTEGER*8 result. Use this function in programs that are intended to
run in both 32-bit and 64-bit environments. Be sure that variables
receiving the result from MALLOC64 are declared INTEGER*8 or POINTER.
NOTES
Compiling to run in a 64-bit environment means compiling the program
with -xarch=v9|v9a and executing on a 64-bit SPARC V9 or UltraSPARC
processor in a 64-bit Solaris operating environment.
