malloc in assembly 8086 -

i need receive input user , required use malloc init buffer first. can't find example online.

this buffer:

 section .bss         buffer:                 resb 80                     ;store input 

how done? ok? (it compiles don't think works...)

    push 80     push buffer     call malloc     add esp, 8  

or maybe this? (this doesn't compile)

push 80 push buffer call malloc add esp, 8  mov buffer, [eax] 

the thing when give buffer input 0, prints 2608 instead of 48 ascii value should print.

input 1 -> gives 2609 accordingly. guess somehow buffer has values it's not supposed have.

this fgets part (it works ok)

 push dword [stdin]             ;fgets need 3 param     push dword 80                   ;max lenght     push dword buffer               ;input buffer     call fgets     add esp, 12                     ;remove 3 push stuck 

and print part:

push dword [buffer]             ;push string stuck push int_format                     ; int_format:db "%d", 10, 0 call printf              add esp, 8              ;remove pushed argument 

malloc has 1 dword parameter, size in bytes allocate, should called:

push <size> call malloc add esp, 4 ; eax points allocated buffer of requested size mov [eax], ebx ; set first 4 bytes of buffer ebx (etc...)
