NAME

librock_replacetabs - Convert tabs in an allocated string to spaces.

#License - #Source code - #Example Use -

SYNOPSIS

#include <librock/parse.h>

char *
librock_replacetabs(
    char ** ppasz, /* Source and destination */
    int tabspacing /* Sets the spacing between repeating tab positions */
);

DESCRIPTION

Inserts 1 or more spaces for each \t (== ASCII TAB == 0x09) found in ppasz, so that the count of characters up to the next character is a multiple of tabspacing.

Typical use, to insert spaces for tab positions 8 characters apart:

#ifdef librock_TYPICAL_USE_replacetabs
    char *asz =0;
    librock_astrcpy(&asz,"0\t1\t2\n");
    librock_replacetabs(&asz,8);
    printf("%s",asz);
#endif

or to replace tabs in a file

char *asz = 0;
while(afgets(&asz,stdin)) {
    librock_replacetabs(&asz,8);
    printf("%s",asz);
}

USES

  memchr
