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; }
