strtrim - remove leading and trailing whitespace
#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)
