error in trim_copy() was a typo: "ouput" -> "output" (but no segfault)
error in trim_nocopy() was an undeclared variable (that also needs to be initialized. segfault, if the new variable is not initialized and the string contains no nonspace characters)
btw. trim_nocopy() has no real practical reason to exist. It is only to show that a left trimming can be done without writing to the string at all, just by changing the start pointer. Also right trimming can be done by just writing a zero after the last nonspace. In fact the trim_copy() function is the one you should always use, both for in place (input==output) or copying operations. Also it makes sense to switch the parameters, so they are in sync with other c std lib string functions like strcpy() and strcat().

My idea (without testing)

strltrim
STRLTRIM(3pub) C Programmer's Manual STRLTRIM(3pub)NAME
strltrim - remove leading whitespace from string
SYNOPSIS
#include <publib.h>
char *strltrim(char *s);
DESCRIPTION
strltrim removes all leading whitespace characters from the beginning of a string, by moving everything starting from the first non-white-
space character to the beginning of the string. As whitespace is counted everything for which isspace(3) returns true.
RETURN VALUE
strltrim returns its argument.
EXAMPLE
To remove all indentation from all lines in a program, you might do the following:
#include <publib.h>
int main(void) {
char line[512];
while (fgets(line, sizeof(line), stdio) != NULL) {
strltrim(line);
printf("%s", line);
}
return 0;
}
