NAME

librock_VSBDeleteAtPtr - remove section of buffer starting at pointer
librock_VSBInsertAtPtr - insert section of buffer starting at pointer

#License - #Source code - #Example Use -

SYNOPSIS

#include <librock/mstruct.h>

char *librock_VSBDeleteAtPtr(
    struct librock_VSB_s *v,
    char *ptr, int len);

char *librock_VSBInsertAtPtr(
    struct librock_VSB_s *v,
    char *ptr,
    const char *src,int len);

DESCRIPTION

These routines allow removing or inserting characters in a librock_VSB with the location given by a pointer. Since VSBInsert and VSBDelete will cause pointers to become stale, this provides a useful alternative. Returns pointer at same position in the possibly moved buffer.

Typical use is

#ifdef librock_TYPICAL_USE_VSBInsertAtPtr
    #include <librock/mstruct.h>
    struct librock_VSB_s *v = librock_VSBalloc();
    char *ptr;

    librock_VSBAppend(v,"This is a test.",15);
    ptr = memchr(v->buf,'.',v->inbuf);
    if (ptr) {
        ptr = librock_VSBDeleteAtPtr(v,ptr,1);
        ptr = librock_VSBInsertAtPtr(v,ptr,"!!",2);
    }

    printf("%s\n",librock_VSBsz(v));
    librock_VSBfree(v);
#endif

USES
