.TH VENTI-MEM 2 .SH NAME vtbrk, vtmalloc, vtmallocz, vtrealloc, vtstrdup, vtfree \- error-checking memory allocators .SH SYNOPSIS .ft L #include <u.h> .br #include <libc.h> .br #include <venti.h> .ta +\w'\fLvoid* 'u .PP .B void* vtbrk(int size) .PP .B void* vtmalloc(int size) .PP .B void* vtmallocz(int size) .PP .B void* vtrealloc(void *ptr, int size) .PP .B char* vtstrdup(char *s) .PP .B void vtfree(void *ptr) .SH DESCRIPTION These routines allocate and free memory. On failure, they print an error message and call .IR sysfatal (from .IR perror (2)). They do not return. .PP .I Vtbrk returns a pointer to a new, permanently allocated block of at least .I size bytes. .PP .IR Vtmalloc , .IR vtrealloc , and .I vtstrdup are like .IR malloc , .IR realloc , and .IR strdup , but, as noted above, do not return on error. .I Vtmallocz is like .I vtmalloc but zeros the block before returning it. Memory allocated with all four should be freed with .I vtfree when no longer needed. .SH SOURCE .B /sys/src/libventi .SH SEE ALSO .IR venti (2)
