Note to anybody copying code: both of calv's examples will segfault as posted. I have not had time to mess with it. On Monday I can get time to post something.
Segfaults on the condition when there are no spaces in the string, for example.
Plus undeclared variables.... maybe someone else can fix it.
edit: corrected code
Code:
void trim_copy(char *input, char *output)
{
char *end =NULL // ouput;
char c;
// skip spaces at start
while(*input && isspace(*input))
++input;
// copy the rest while remembering the last non-whitespace
while(*input)
{
// copy character
c = *(output++) = *(input++);
// if its not a whitespace, this *could* be the last character
if( !isspace(c) )
end = output;
}
// white the terminating zero after last non-whitespace
if(end!=NULL) *end = 0;
}
Code:
similar changes are needed for the other example, trim_nocopy();

Hi,
What sed command (if sed is the right command) can remove ALL white space from my file. I have a csv, except I want to remove all white space between commas and characters.
My idea (without testing)
sed 's/ //g'
Is there a better way? (18 Replies)

punycode_decode(3) libidn punycode_decode(3)NAME
punycode_decode - API function
SYNOPSIS
#include <punycode.h>
int punycode_decode(size_t input_length, const char [] input, size_t * output_length, punycode_uint [] output, unsigned char []
case_flags);
ARGUMENTS
size_t input_length
The number of ASCII code points in the input array.
const char [] input
An array of ASCII code points (0..7F).
size_t * output_length
The caller passes in the maximum number of code points that it can receive into the output array (which is also the maximum
number of flags that it can receive into the case_flags array, if case_flags is not a NULL pointer). On successful return it
will contain the number of code points actually output (which is also the number of flags actually output, if case_flags is not
a null pointer). The decoder will never need to output more code points than the number of ASCII code points in the input,
because of the way the encoding is defined. The number of code points output cannot exceed the maximum possible value of a
punycode_uint, even if the supplied output_length is greater than that.
punycode_uint [] output
An array of code points like the input argument of punycode_encode() (see above).
unsigned char [] case_flags
A NULL pointer (if the flags are not needed by the caller) or an array of boolean values parallel to the output array. Nonzero
(true, flagged) suggests that the corresponding Unicode character be forced to uppercase by the caller (if possible), and zero
(false, unflagged) suggests that it be forced to lowercase (if possible). ASCII code points (0..7F) are output already in the
proper case, but their flags will be set appropriately so that applying the flags would be harmless.
DESCRIPTION
Converts Punycode to a sequence of code points (presumed to be Unicode code points).
RETURN VALUE
The return value can be any of the Punycode_status values defined above. If not PUNYCODE_SUCCESS, then output_length, output, and
case_flags might contain garbage.
