strltrim - remove leading whitespace from string

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

strltrim removes all leading whitespace characters from the beginning of a string, by moving everything starting from the first non-whitespace character to the beginning of the string. As whitespace is counted everything for which isspace(3) returns true.

strltrim returns its argument.

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; }

publib(3), strrtrim(3), strtrim(3), isspace(3)
