int G_getl | ( | char * | buf, |
int | n, | ||
FILE * | fd | ||
) |
Gets a line of text from a file.
This routine runs fgets() to fetch a line of text from a file (advancing file pointer) and removes trailing newline.
buf | string buffer to receive read data |
n | maximum number of bytes to read |
fd | file descriptor structure |

int G_getl2 | ( | char * | buf, |
int | n, | ||
FILE * | fd | ||
) |
Gets a line of text from a file of any pedigree.
This routine supports text files created on various platforms (UNIX, MacOS9, DOS), i.e. \n (\012)
, \r (\015)
, and \r\n (\015\012)
style newlines.
Reads in at most n-1 characters from stream (the last spot is reserved for the end-of-string NUL) and stores them into the buffer pointed to by buf. Reading stops after an EOF or a newline. New line is not stored in the buffer. At least n bytes must be allocated for the string buffer.
buf | string buffer to receive read data, at least n bytes must be allocated |
