strtrim

#include <publib.h>
char *strtrim(char *s);

strtrim removes all whitespace characters from the beginning and the end of a string. As whitespace is counted everything for which isspace(3) returns true.

strtrim returns its argument.

To remove whitespace from the beginning and end of all lines, you might do the following:

#include <publib.h>
int main(void) {
	char line[512];
	while (fgets(line, sizeof(line), stdio) != NULL) {
		strtrim(line);
		printf("%s", line);
	}
	return 0;
}

publib(3), strrtrim(3), strltrim(3), isspace(3)
